parallax power supply 7345ru parts PWM
My 7345 is not charging the coach batteries but does supply 12power to all accessories. The transformer, fan and relays work fine. Think i need a PWM circuit for it. Contacted PP tec support and th...

This is getting over complicated. Even the 7345 may have a resting voltage of 13.6 but the PWM should, at least in theory be able to get over 14v if it correctly senses the battery's are that low. OF coarse I can't even confirm the 7345 has a PWM charging circuit. The assumption is based on the 6300 series (wich it replaced did)
Realistically a 12v 50amp batter charger could be purchased for less then all these options. Start the generator, plug in the charger and off I go. Or even get an alternator connected to the generator's crank shaft :-)
Large guage wire is definitely important though. The 7345 has 10 or 8 guage wire on it. But for a max of 45amp at a distance of less then 10feet should be sufficient.
I've got the unit out and disassembled. I'll order the parts. If it fixes it great, if not I'll buy a decent automotive charger.
