fusible link questions

[dirtwarrior17]

Ok i've had no power for about 3 weeks now and I've come down to attacking my K5 with a voltmeter in every possible problem location and im tired....

I know there is only a few places that could blow a fusible link and kill ALL power but i don't know where they are..

what fusible links would disable power? i don't have anything with power

i thought it was the starter wire but i definetly have a fusible link blown somewhere.

appreciate the help....

IIRC, there are 2 wires going to the starter besides the battery cable. both of these should be fusable links, one wire goes to the fusebox and the other goes to the alternator. ill try to find my haynes manual and look at the scematic.

Do you know if its the big stud or the little stud on the solenoid?

doh, i forgot about the wire for the ignition switch.

both fisable links would go to the big stud, same as the battery cable. only i wire goes to the small stud, that comes from the fusebox area also.

Someone else recently had a similar problem and it was corrosion inside the wire cover of the fusible link, IIRC.

As I suggested to him, I replaced mine in each Chevy truck I get with 50 amp or 60 amp circuit breakers so they reset if there is a problem. At the same time I do the remote solenoid install so there is only one wire (large gauge) going to the starter and it isn't hot unless you're turning over the starter. Up to '86 at least it is simple. not familiar with the newer style alternator and wiring , supposedly it changed some.

got one.... just little easier to type a few words than try to find my way through that mess and it's not gonna say which ones cut all power... it would but i don't feel like looking for an hour.
