Sybersteve Posted June 9 Share Posted June 9 Hi, I have a Carado T449 Motorhome and have the following problem. On travelling to the south of Spain I used the French aires as overnight stops and relied on battery power for the 4 days travel from home to the camp site. The battery did not move from the full position at all, we had the overhead fan on each night, had a cool box running on the leisure battery as well as lights, fridge and water etc. when at the campsite on electric hook up the leisure battery dipped to half full after 3 days and died completely on day 5. I disconnected the electric hook up and started the Motorhome for a few minutes and the leisure battery was at half power again. This enabled me to again run the fridge, but had to be repeated every day. When the holiday was over on the drive back the leisure battery registered full each day and everything was used on 12v, showers, cool box, fans etc. I know that the battery is approximately 7 years old and it wouldn’t hurt to replace it, but any idea why the battery was not charging on electric power and possibly being discharged on site? Any suggestions would be appreciated, as I guess that just replacing the battery will not solve the issue. Regards Steve Quote Link to comment Share on other sites More sharing options...
rayc Posted June 9 Share Posted June 9 Have you confirmed the ehu charger is working? What is the battery terminal voltage when it is on? Quote Link to comment Share on other sites More sharing options...

Robinhood Posted June 9 Share Posted June 9 It could be any number of things, but assuming Schaudt electrics for a Carado, one easy initial check would be the (nominally) 20amp fuse on the Electroblock for the internal charger (probably marked "Internes Ladenmodul") 1 Quote Link to comment Share on other sites More sharing options...
Sybersteve Posted June 9 Author Share Posted June 9 I’m on my way home so will check when back home on Tuesday just checked the fuse as you suggested and it has blown, so thanks for the replies 👍 Quote Link to comment Share on other sites More sharing options...

Robinhood Posted June 9 Share Posted June 9 Fuses do sometimes blow "spontaneously", but if you replace it (same rating) and it goes again you'll need to look for the underlying cause. Quote Link to comment Share on other sites More sharing options...
Sybersteve Posted June 9 Author Share Posted June 9 Yes fingers crossed that this an easy cheap fix for a change 😎 Quote Link to comment Share on other sites More sharing options...
