RedBox is an 85 GLH-T running 89 TII wiring from a Lebaron GTC, it's recently assembled and has about 2K miles on it's current set up. It made it from SDAC 26 in Memphis to Flagstaff AZ thanks to Rhymes-with-Tortoise X2 where it burned out the SMEC 'driver' board. It does have a socketed 'brain' board and custom cal but that board seems to be surviving just fine. I replaced the driver board with a spare after dragging RedBox home from PHX area on a car dolly, threw the replacement driver board in it and after just a few miles it bucked a couple times then lost all power. No spark, no fuel and curiously the ASD relay is clicking like mad. This is the exact same thing it did in flagstaff a few days and about 10 actual driving miles ago. Even bypassing the ASD does nothing, still wont run.
So before I throw ANOTHER driver board at the problem(there is nothing visually wrong with either board), Id like to figure out the cause-usually the hardest part I'm thinking a crossed or chaffed wire? The harness has been gone thru for this build, wires checked visually and entire harness retaped.
Any ideas on the cause or places to look? So far Iv'e just checked the injector harness behind the valve cover but don't see any issues there. I suppose I should be checking for continuity or Ohming everything out but I'm not very good with electrical
This is a shot of the 'test' just plugging the small 12 pin harness to another SMEC before disassembly and reassembly into the in car SMEC. It fires right up like this and I suspect when I do this type of test again today it will too. I'm going to Cars and Coffee right now (WHERE REDBOX WAS SUPPOSED TO DEBUT TODAY) then a funeral for a coworker so I wont be able to test anything for several hours. Hopefully I'll have some good suggestions by then
