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...

Again, that's just an IR drop within the converter. The converter has a series resistance of about 4 mohm that's outside of the regulation loop. 4 mohmn is on the high side, so in addition to wiring and trace losses, there may also be an emi filter involved.
If the 73xx has a similar internal line drop, then Phil should be seeing a drop of 0.004 ohm * 0.2A = 0.8 mV drop at the converter when turning on a led light. That's extremely insignificant.

The Paramode 4455, a follow up to the 7355 in the product line, has these voltage curves which show the sag under load.
