I have 7 positive wires (not counting main battery cable) attached to my chassis battery. I recently had my battery replaced by Mastertech and now I have an intermittent issue where my tranny key pad flashes very briefly on ignition but that's it. No power to neutral relay coil. These 7 wires consist of one 20 amp in line fuse, three 10 amp and three 7.5 amp fuses. Does anyone know which of these would power the Allison 3000 ECM? I heard there should be 2 wires for the tranny? The 20 amp fused wire has a butt connector that looks a bit suspect. Would the 20 amp fuse be wired to the tranny?

That would be the one , if it's anything like my coach.
20 amp on mine, is the trans feed.
Solder your connections , butt connectors will always fail , if exposed to the weather.

I'm curious why you are starting a new thread when I thought Mike Canter and others had made suggestions on your previous one?

I was specifically asking for the amperage of the fuse(s) the Allison direct wires to the battery. (20Amp? 10 Amp or 7.5Amp) That question was not answered in the Monaco forum so I thought I'd ask of the Allison forum where experts of the tranny may lurk whilst not purveying the Monaco forum where the question was recently posed.

I think I've identified 2 of the 7. In my case the Allison keypad gets 12v from one a 10 amp direct wire. My only 20amp fuse that is direct wired is from the RV30D solar charge controller. It has voltage while unhooked from the battery (since it's a charge feed) so I had to cover the solar panel. 2 of 7 identified.

I had that happen after a visit to Cummins and they disconnect the battery. They did not tighten the nuts on the wires coming off of the battery cable post.
