PD9260 Convertor Never Goes To 14.4V

Yes it is a HUGE DIFFERENCE and that's why I'm trying to figure out why my PD9260 does not go into boost mode. I have no clamp-on amp meter, but amps do show in my Trimetric. I haven't looked at amps in the Trimetric other to see that they are higher when the converter 1st starts, then tapers off as time goes on. My battery was about 35% discharged, a significant amount. I expected the PD9260 to start out in boost mode, then drop back to absorption rate, but it doesn't.

Do I have to discharge the battery 50% to get boost mode, or 60%, or 70% ??

I totally empathize with your frustration. Before I purchased the PD9260C, I tried everything to get the WFCO8955 into bulk/boost mode. It was so frustrating to have to spend almost $200 just to get the bulk/boost mode the WFCO8955 was designed to deliver in the first place.

Anyhow, back to the topic at hand. Seems we started out trying out to determine whether you were in bulk/boost or not, but now it seems to have gravitated towards why the PD9260C hasn't gone into bulk/boost mode on its own.

I believe the Charge Wizard Pendent will go a long way in addressing both of these issues. When the PD9260C is OEM packaged, the pendent is included with the PD9260C. The small pendent (with 5-6 ft of wire) plugs into a small RJ type connector on the side of the unit. It does two things, one, it tells you what charging stage/mode is currently active (LED steady on, bulk/boost; LED blinking quickly, absorption; LED blinking slowly, float), and two, it allows you to push a button and manually change the charging stage/mode to one of your choosing.

The PD Charge Pendent is only $10-$20. I'd recommend purchasing one. That's a small price to pay to know what the PD9260C is thinking--even for troubleshooting purposes. Plus, if you disagree with it's logic, literally, you have the option of changing it. That's a lot of flexibility for less than $20!

My two cents . . .
