alternator tests ok on bench but does not put ou any voltage when run through the wiring harness?
tach, speedo and temp guage don't function all fuses
ok any clues as to where to look appreciated figure the ecu may be wacked out
Could be the ECM, or it could very well be a short in the wiring harness leading the alternator not to charge. Try replacing or testing the battery -- Many newer alternators WILL NOT put out a charge if the battery is at less than 12 volts. This is a safety feature to ensure that the alternator doesn't burn itself out trying to charge a dead battery. This might also explain lack of dash component function.
put hot battery in 12.6 volts. tach and speedo went away before battery went dead will ring out the wiring and I have another ecu comming Thanks
