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...

Paralleling the 7345 with another charger in order to increase current won't work. The higher voltage source will do all the work. The lower voltage source will be back biased. But, if you like kluges, go for it.
Regarding your claims that the mod has the potential of starting a fire within the cable. I see now you're backing off a bit. Now you're saying the cable must be undersized. 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.

In the final analysis, your mod is a great hobby project to demonstrate getting around a product's deficiencies. In the long run, I'll probably do what MEX and BFL13 do - use an inexpensive high voltage charger in parrallel with a 7345 to up the current a bit when charging my AGM batteries, as they charge so fast anyway even with only voltages in the 13.8 range.
