Help my truck keeps running the battery dead after sitting for two days. It is a '86 F-250 XLT with the 460cid. I have a Haynes manual but I can't understand the diagrams. They don't match the wiring in the truck and are very confusing. Anyone know where I can get a wiring diagram that is easier to understand? I had the battery checked at the local parts store and they said it was good. I even put in a new alternator. Also for some reason the ammeter doesn't register anything!? The reason I got a new alternator was because it had a GM alternator on it with a small bulb connected in the wiring.
is that all about? I removed the bulb and connected the wiring harness the way the manual says.
I pulled all the fuses, made sure everything it off and connected a bulb between the + of the battery and the wires that are on the starter relay ,one by one. I have narrowed it down to two wires but with out understanding what is printed in this Haynes manual I'm lost.
