aressee Posted December 17, 2019 Share Posted December 17, 2019 I've got a Waeco 500 watt inverter, fitted as standard 5 years ago in my motorhome. First time away for a year, the inverter has decided not to work. It shows the green light and makes all the right noises but the red warning light is flashing slowly. There is 13.4 volts going in but nothing coming out. Has anyone had this problem or can anyone suggest where to start looking. Thanks Link to comment Share on other sites More sharing options...
spirou Posted December 17, 2019 Share Posted December 17, 2019 Fuse? Not much else you can fix most likely. Link to comment Share on other sites More sharing options...
aressee Posted December 19, 2019 Author Share Posted December 19, 2019 Thanks Spirou Took the lid off the unit and found two 35amp bayonet fuses, thought 'great' problem solved - no chance- both fuses are ok. The unit is fixed under the floor and looks brand new both in and out, but I think its time to chuck it and go for a new one, possibly 1000w Regards Link to comment Share on other sites More sharing options...
Ninian Posted December 19, 2019 Share Posted December 19, 2019 Hi, Are you sure the unit doesn't have a reset button or a thermal overload link. Link to comment Share on other sites More sharing options...
Cattwg Posted December 20, 2019 Share Posted December 20, 2019 Just a thought and not wishing to “teach my granny ….…” Did you check the fuses with a meter and not just a visual inspection? I’ve has fuses that looked OK but in fact were faulty. Cattwg :-D Link to comment Share on other sites More sharing options...
aressee Posted January 4, 2020 Author Share Posted January 4, 2020 Hi Ninian Thanks for your reply So far I have checked the voltage in and out, checked the amps in, checked the fuses with meter, tried a new battery and tried new leads and still its not working. There is no reset button that I can see but I'm not sure what I'm looking for when you say a thermal overload link. Is this mechanical or electrical.

John52 Posted January 4, 2020 Share Posted January 4, 2020 aressee - 2020-01-04 6:52 PM when you say a thermal overload link. Is this mechanical or electrical. Cheers It will take the form of a bi-metallic strip in the circuit - thats 2 strips of different metal sandwiched together, one expands more than the other, so when the strip heats up it bends breaking the circuit. When it cools it should bend back reconnecting the circuit. (There is one on the windscreen wiper motor) Link to comment Share on other sites More sharing options...
