Truck owner called yesterday from the airport as he was boarding to fly home. Told me to meet him at his garage this morning at 9am central. Took my test light and multimeter along with my box of electrical tools/supplies. My first round of tests determined no power to the inside fuse box or through the fuses. The under side of the dash looks like a birds nest of multi colored wires. But my job was to get it starting again with the key. Knowing the fuse block gets its power from under the hood i took my test probe and moved there. Started looking for fusible links in the positive wires. I noticed a separate wire (mounded into the cable fitting) coming from the positive battery cable that had a fusible link in it. Yes bartamos it had a fusible link! I tested the link and it had power but upon following the wire I found it had come loose from a crimp connector near a relay on the radiator core support. Cut and cleaned both ends and did a proper splice and lo and behold the truck started right up and all the accessories worked. Since I had accomplished the job requested I packed up my stuff and had a long discussion with the truck’s owner about underdash fires caused by faulty wiring. He promised to add a rewire to his to do list. He’s happy, I’m happy, time to work on my stuff now.
