Hello all. I'm having an electrical issue and this looked to be the best place to post about it. The other day, we went to move the dump truck and it wouldn't start. This has happened a few times so I figured it was time to see what was going on. So i put it on a charger for most of the day and got it into the shop.
Load tested both batteries and they tested good. Alternator is putting out 14.2 volts. Disconnected both batteries and tested for draw, and it has a 1.5 amp constant draw.....a bit too much I believe. Next i start pulling fuses to pin point further. #2 10A circuit that the Owners manual simply calls "Cluster" (in addition to fuse #35 for Instrument Cluster).
I have a Haynes manual covering 1999-2006 F-250 & 350 Super Duty, but cant find that particular fuse or the corresponding circuit. If anyone has some insight into this, I would greatly appreciate some guidance.
I could just put a battery tender on it and not worry about it, but I like a good electrical challenge
Thanks in advance.
EDIT: I've noticed that when the #2 fuse is pulled, it does NOT affect instrument cluster operation, although it did seem to idle a little rough. So I'm wondering what "cluster" the owners manual is talking about. Odd. Going to be a nice head scratcher.
