Need Help Finding Location Of Wire


randyt

Recommended Posts

I changed the transmission filter and fluid on my 92 LS. After removing the jackstands and lowering the car, I found it would not start. IT CRANKED FINE!

I checked my Lexus service manuals and found there was no voltage on the contact of the master ignotion relay. This voltage is supposed to come from the fusible link #2 directly to the relay contact. For the life of me I can't figure the PHYSICAL location of this wire. I ran jumper from the ignition switch and it starts and runs fine. I'm worried though, if this wire has broken are there others dying too? Please help!

randyt,

Looking at my schematics for the 93 LS and apparently there are differences between the 92 and 93 LS, surprisingly. I can't even find a master ignition relay in the 93 schematics. For the 93, a 30A fuse link located in the F11 fusible link box powers both the starter and the ignition circuits. Do you have the Electrical Wiring Diagrams which are in a separate manual? The Electrical Wiring Diagrams Manual is pretty good at giving locations of the various components. For the 93, the ignition circuits are powered by a black wire with an orange stripe coming off the ignition switch. Just where did you install your jumper wire to get it to run? I will be happy to help if we can find some commonality between the 92's and the 93's.
