I was going through the wiring on my 1969 G-10 V-8, and found a black small gauge black wire hanging loose by the starter solenoid area. The wiring print does not show a black wire in that area even though this one is in the wiring harness with the others. that's the first mystery. When tracing small black wires further, I found a second light gauge black wire with a white stripe and an inline fuse in the factory wire loom, by the voltage regulator. I need to know how these wire into the system since they don't show up on harness the wiring print, and what fuse size goes into the fuse holder. this fuse was corroded beyond recognition.

Re: Factory in line fuse question
Is the boost wire to the coil connected to the R terminal on the solenoid?

Yes it is. It's a yellow small wire.

Re: Factory in line fuse question
Well hook a test light to juice, and touch the wires, if it glows, that means its hooked to something,,,,then try 12 volts to them to see what comes on,,,if its small gauge, that could of been for a light, radio, alarm, CB, voltmeter, relay for fog or driving lights or tachometer......I dont know that they would put an inline fuse in the doghouse.....

Re: Factory in line fuse question
This is an existing wire inside the factory wiring harness, so I believe it is not for an aftermarket accessory or the radio since it is hanging loose by the starter solenoid. The only black wire in the wiring print that is in that area is the fusible link. I am wondering if this wire is the link, and has been replaced by the large red wire that is coming from the starter solenoid to the terminal block on this van. This van was an original camper conversion, and does have a roof top Air Conditioner, and the extra load may have been too much for the fusible link. I don't know, Im just guessing at this point. Help me out if you know where the other end of the link should come out, so \i can look for it without Destroying the entire wiring harness.donivan65 wrote:Well hook a test light to juice, and touch the wires, if it glows, that means its hooked to something,,,,then try 12 volts to them to see what comes on,,,if its small gauge, that could of been for a light, radio, alarm, CB, voltmeter, relay for fog or driving lights or tachometer......I dont know that they would put an inline fuse in the doghouse.....

Re: Factory in line fuse question
That should be a 16 gauge fusible link wire from the positive battery cable to the junction block,,,,but test the hanging wires with a test light,,,,hook it to the positive battery cable or alternator output, see if the wires read NEGATIVE,,,,,,,,hook the test light to ground, turn key on and see if the wires or fuse holder read POSITIVE,,,,see whats in those wires,,,,,,,,,,if they are dead, hook juice to each one,,,,then hook the test light to ground and see if that juice comes out in the fuse holder or other wires
