Do you happen to have any pictures of this modification? I am going to purchase a pd9270 from best converter and would like to be able to charge my Trojan batteries at their recommended charge rate of 14.8.

You could just as well get the adjustable voltage 70 amp PowerMax Randy sells and set it to 14.8 or whatever you like. (EG, at 32F, 14.8v becomes 15.2v to get the same results as 14.8 at 80F) Adjustable is the way to go!

Also the PowerMax 70 amper is PF corrected so it doesn't take as much of a generator as the non-PF corrected PD 70 amper does.

However if you insist on the non-adjustable converter version, you might want the PD with its Charge Wizard instead of the PowerMax depending on what charging profile you need. "It depends" (as usual)

IMO it is a "no-brainer" to get the adjustable voltage converter that can do it all with less generator required!

What voltage do the 9245c's usually max out at?

14.4v if the Wizard pendent is installed. Otherwise, 13.6v.

9100's need the pendant/wizard to become a 3 stage converter. 9200's have it built in and if you have the Wizard then you can control what stage you want and the flashing led will tell you the stage it is in.

How about using a 10-turn cermet? The best of all worlds?

"KJINTF, the suggested 60k resistor on pin #5 will not change Normal or Float mode?"

Modified a few of the PD's - They keep a rock solid 13.2 / 13.6 / 14.9 (14.9 is set by the resister size)60K is only a suggestion - you will need to experiment

Did a similar modification on my WFCO 75amp plus added a remote control which manually selects 13.2 / 13.6 / 14.9 works good to shorten gen run time

I wonder if this is a Randy custom modification or if PD made a special batch for Randy.

KJINTF, the suggested 60k resistor on pin #5 will not change Normal or Float mode?

I would be curious if amps still sag as PD is known for. Also if this unit will still run on a Honda 1000?

Nice.
