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...

Yeah, 16 awg might become a concern. But 16 awg cable has resistance that's way too high (4 mohm/ft) to be used for charging batteries. It would never work! I have 23 feet of cable (one way). The voltage drop at 45A is 4.1V! That's absurd to think any MH manufacturer would install 16 awg wire. In other words, there's never a chance of starting a fire with an undersized charging cable.

Here's a quiz question for you. At 45A, what's the largest gauge cable that will start a fire? We'll assume if you don't provide an answer then it's not an issue.
Maybe 16 awg might (eventually) heat up enough when carrying 45 amps so as to start a fire (eventually) ... perhaps even 14 awg might be a concern (eventually).
