ACG fuse blowing, main relay?
post re-awakening... HappyThanksgiving
read some suggestions here and elsewhere to come to following:
TL 2000 won't start - ACG S fuse blowing
Electrical (logical) troubleshooting
ACG S fuse (under hood/engine fuse box) is blowing… various posts indicate alternator, fuel pump, main switch relay… etc
Most posts indicate a short to ground in one of these areas… connections/wiring.
I have learned that there are various checks (sounds, voltage, etc) to pay attn to when turning key to diff positions
One area is the main switch relay that provides various clicks… I can actually reach up under dash/console with left hand and put fingers on main relay switch.
With turn to On… relay clicks (and fuel pump should actuate (sound)
With turn to Start… engine should turnover
With turn (back) to On… relay clicks
I have done following… with good ACG S and Fuel pump(inside electrical box - driver side) fuses
Disconnected fuel pump electrical connection
Turn key to On… main relay clicks… (no fuel pump sound [actually wasn't before disconnect either])
Turn key to Start… engine turns, but does not start (shouldn't anyway without fuel)
Turn key to back to On… relay clicks
Turn key to off
Turn key to On… no main relay click
Check ACG S fuse < blown
If I replace ACG S fuse and pull the Fuel pump fuse
Turn key to On… no main relay click (ACG S fuse not blown -? due to removal of Fuel pump fuse)
Turn key to Start… engine turns over - no start(shouldn’t w/o fuel)
Turn key to On… ? Cannot remember if click or not.
So, seems issue is between Fuel pump fuse and fuel pump connection.
Anyone have the diagrams for this circuitry and/or any further suggestions/guidance.
