Broken wire draining battery
I have developed a short. The battery will drain in 2 or 3 days. I disconected the neg. at the battery and connecterd a multimeter. I get between 2 and 3 volts. Pulled every fuse, disconected the Alt., plow, and key switch at the relay, no change.
On the starter relay, battery side I have 3 wires; + Bat, and 2 eye conecters 1 with 2 wires(orange) and 1 with 1 wire(red). The 2 orange wires pull .6 volts, is this normal? The truck has a clock but its burn't out. The red wire pulls 2.2 volts. But heres the kicker, about 2" in the wire is broke inside the casing. Where do these wires go? The orange wires power the dash as it acks like a dead bat when its diconected. Could this have something to with the hard cold stating?

wiring
What year is the truck and what engine does it have? I have some wiring diagrams and might be able to look it up. One big cause of battery drain is the charging system, voltage regulator and alternator. There are usally fusible links in these wires.

I disconnected everything;
Voltage Reg.
Duraspark
coil
dizzy
Alternator
starter
all the fuses are laying on the floor
Now when I connect the voltmeter it starts at 10-11 volts then slowly goes down to 2.
The 2 wires that come off the relay blk w/ orange stripe and a double wire both yellow.
Leave the double yellow connected I get a draw of 1.5 volts.
Leave the blk / org connectec the volts spike to 10 - 11 and slowly go down to 2
Disconnect both, 1.5 volts
I'm thinking relay, which I'll pick up tomorrow, or the dang start switch. Whats left? Dirt?
