PD 9260 Issue

I have a 9269 that I bought from Best in May of 12. Recently the pendant stopped working, so I bought a new one and installed it a couple of weeks ago. It changes mode as it should now.

I'g getting ready for a 2 week trip this weekend and I was checking out all the systems. I cycled the pendant on the 9260 and all the correct voltages showed up on the Trimetric, BUT no amperage at all zero, zip. In fact, the Trimetric showed -.4amps which is my normal parasitic for what I had on. Confirmed the voltages with a VOM on the battery and they matched Trimetric.

I left the old WFCO installed and when I switch to the WFCO, amperage an voltage reads as anticipated on the Trimetric.

I called Randy at Best and he was not able to help over the phone.

Has anyone experienced this situation and is there a cure other than replacement.

I can live with the WFCO for this trip, but it never goes into boost and that means longer recharge times.

  • If you have the chassis ground to frame connected (as is proper) on the deck- mounted 9260, is it possible the voltage is showing on the batts (from 9260 POS output and frame) but no amps to batts because the 9260 DC NEG output path is "open" ? I assume that NEG output path goes via Tri shunt, but is open before reaching the shunt.

    Not sure that would explain it, but giving it a try :)

    But I connected a 2-farad cap through a 50-amp switch and my stupid Wifco sucks it up hook, line & sinker. Goes into boost. Wonder when the cap is going to grenade?
