bikerstew Posted April 12, 2023 Share Posted April 12, 2023 Hi All I have an Autocruise Starburst and i have accidentally pulled the 3 wires out of the square 4 pin plug that plugs into module A and goes to module B while hoovering. Does anyone know which wire goes to which pin any help greatly appreciated Link to comment Share on other sites More sharing options...
Labby Posted April 12, 2023 Share Posted April 12, 2023 If you go to the www.apuljackelectronics.co.uk web site , and look at their catalogue , in the Autocruise section is photos of the A and B modules with some connections information shown which may help .

Derek Uzzell Posted April 13, 2023 Share Posted April 13, 2023 bikerstew There are some photos of the modules in my posting of September 20, 2020 in this forum thread https://forums.outandaboutlive.co.uk/topic/50205-autocruise-starspirit-problem/ The 2nd and 3rd photos are (respectively) a side and end view of Module A. However, although the first of those photos shows that the 4-pin socket is a "Module B Connection" and the second shows the socket itself, that's no help regarding the way in which the wires fit into the plug that goes into that socket. (My 2020 posting also has a wiring diagram, but that's no help either.) Suggest you do as Labby suggests and contact Apuljack Electronics. If they can't help and you can't find anyone who can give a certain answer, you may have to resort to educated guesswork. Assuming that there is a similar 4-pin socket on Module B (and you can access Module B) it's (sort of) logical that the wiring of the plug that goes into the Module B socket will match that of the plug that goes into the Module A socket on a pin-to-pin basis. The plugs should only fit into the sockets 'one way up' - so, if the position in the Module A plug of the wire that was not pulled out matches the position of the same colour wire in the Module B plug, there's a reasonable chance that the position of the other 3 wires in the Module B plug will be the same for the Module A plug on a wire colour-for-colour basis.

bikerstew Posted April 13, 2023 Author Share Posted April 13, 2023 Hi and thanks for the replies I have emailed Apuljack electronics a few days ago and as yet havent had a response the cable that plugs in to module A is hard wired into into module B Link to comment Share on other sites More sharing options...

Derek Uzzell Posted April 18, 2023 Share Posted April 18, 2023 Unfortunately, photos won't help. This 2020 forum thread includes several photos relating to the "Energy Management System" product that Autocruise used to install. https://forums.outandaboutlive.co.uk/topic/50205-autocruise-starspirit-problem/ The photo below shows the 4-pin socket (arrowed in red) in Module A into which the plug on the end of the cable that leads to Module B fits. As bikerstew said in his last posting, the other end of that cable is hard-wired into Module B, so - even if Module B were opened up (VERY inadvisable) - it would still not be practicable to know how the three wires that were accidentally detached from the Module A plug should be reinserted using wire colour-to-colour 'educated guesswork'.

onecal Posted April 18, 2023 Share Posted April 18, 2023 Hi They just may if he shows the damage done , I am a little puzzled as to why no photo as it may not be actually the same modules Derek as you have posted We wait and see Regards Link to comment Share on other sites More sharing options...
Derek Uzzell Posted April 20, 2023 Share Posted April 20, 2023 Based on bikerstew's postings above, it's clear that his "Starburst" motorhome has the "Energy Management System" (EMS) that Autocruise used to fit. This system was manufactured by a company called "Kigass" (that ceased trading long ago) and was fitted to Autocruise and Bentley motorhomes for a while (and, I believe, to some Murvi models). Problems usually relate to the control-panel and Apuljack Electronics and this company (EMP) http://www.nrgmp.com/repair have advertised a control-panel repair service. I think EMP will be a non-starter nowadays, but in any case bikerstew's problem is not related to the control-panel. There is a cable that goes between the EMS system's Module B and Module A. What is needed is for an owner of an Autocruise motorhome that has the EMS system to check how the 4 wires at the Module A end of the cable connect into the square 4-pin port arrowed in my photo above. Ignoring this recent thread (that MIGHT relate to an EMS system) https://forums.outandaboutlive.co.uk/topic/61537-autocruise-control-panel-problem/#comment-707848 there do not seem to be any other current O&AL forum-members who own Autocruise motorhomes that have (or are likely to have) the EMS system. If bikerstew cannot get a simple answer from Apuljack, I suggest a photo be taken of the end of the cable showing the plug and its detached wires, and the question of which wires go where in the plug be asked on the larger motorhome forums. (Hopefully all EMS systems have the same wire colour-coding for the Module A to Module B cable!) MotorHomeFun and MotorhomeFacts forums are likely to be the best places to enquire https://www.motorhomefun.co.uk/forum/ https://www.motorhomefacts.com/ Link to comment Share on other sites More sharing options...

These three attached images relate to a Module B manufactured in 2007 Image 1: Shows the purpose of the cables that connect to Module B and the sockets into which those cables plug. Image 2: Shows the sockets themselves, with Socket 10 relating to the RJ45 cable that connects to Module A. Image 3: Shows Module B's printed-circuit board with no sign of cable hard-wiring. As I suggested above, if the cable that comes from Module A and plugs into Module B's Socket 10 can be unplugged and the colours of its wiring identified, as one of the 4 wires is still in place in the plug that goes into Module A, there's a good chance that matching the 'colour position' of the Module B Socket 10 plug's wires will produce a successful result.

onecal Posted April 21, 2023 Share Posted April 21, 2023 Derek Maybe bikerstew has different modules that what we are looking at ? The hardwiring of module B is strange ? A photo of both and damage to same would would really help Regards Link to comment Share on other sites More sharing options...
Derek Uzzell Posted April 22, 2023 Share Posted April 22, 2023 There are several on-line photos of the Module A and Module B units and all of them show exactly the same design. Besides which, using the photos above and on the links I provided, it should be straightforward for bikerstew to confirm whether or not his Modules are different in any respect. Regarding the communications cable going into Module B being hard-wired, I'm very doubtful that this is the case. All relevant on-line images of Module B have the four RJ45-type sockets shown in the photo on my last posting and hard-wiring any of the cables that connect to Module B (or to Module A) would seriously complicate installation. On motorhome forums, discussions about problems with the Autocruise Energy Management System have occasionally included complaints about the inaccessibility of the parts that make up the system. Consequently, it may prove difficult for bikerstew to take meaningful photos of Module A and B while those parts remain in situ. A photo of the damaged plug of the communications cable that connects to the Module A 4-pin socket MIGHT be useful, but I've begun to think that - even if the plug at the other end of that cable can easily be removed from its Module B RJ45-type socket - a close inspection made of that plug's wiring may still not allow a reliable decision to be arrived at regarding how the three detached wires of the damaged Module A plug should be reconnected.

Derek Uzzell Posted April 23, 2023 Share Posted April 23, 2023 Not really . It seems to happen quite often on forums nowadays - an initial question and then a deathly hush from the enquiry's originator. I put it down to alien abduction. Link to comment Share on other sites More sharing options...

Derek Uzzell Posted May 6, 2023 Share Posted May 6, 2023 You may well be aware of this, but this company used to offer diagnosis/repair services for Module A and Module B units. http://www.nrgmp.com/repair A Companies House check https://find-and-update.company-information.service.gov.uk/company/06767298 suggests that the company is still active, but whether they are still dealing with the Autocruise system remains to be seen. Even if they are not, they might be able to assist.

onecal Posted May 8, 2023 Share Posted May 8, 2023 Hi I think at this stage ,it may be prudent to replace the whole unit I think his question was the four wires he pulled out of the four pins out of A Any I have worked on has a plug also on B ? Clearly marked 1 2 3 4 5 6 It may be a very old model? Regards Link to comment Share on other sites More sharing options...
Derek Uzzell Posted May 8, 2023 Share Posted May 8, 2023 This is a '2-part' thread, with the initial poster (bikerstew) asking about the wiring of a Module A plug (and stating that Module B was hard-wired - that I'm near certain is not correct). That part of the thread ground to a halt on April 23. The thread was resurrected on May 5 (by wayneA) asking about repair or replacement of Module B. The chances or repairing a faulty Module B, or obtaining a new Module B are very very slim, so Wayne is exploring finding a secondhand Module B unit.
