Timing Light Shows Timing Connected Backwards.

1986 Camaro NO ELECTRONICS

4 Barrel Holley-NON COMPUTER

STAND ALONE DISTRIBUTOR

FORD 5.0 COIL PACK

LOW PSI ELECTRIC FUEL PUMP


Anyhow, everything wired correctly, when at idle checking timing, I only show spark WITH THE NEGATIVE TIMING LIGHT LEAD, ON THE POSITIVE BATTERY TERMINAL, AND THE POSITIVE LEAD ON THE NEGATIVE TERMINAL.



Is this bad? is there an error I can fix?

When I check other cars, the light works great wired correctly to their batteries.

Re: Timing Light Shows Timing Connected Backwards.

Are you sure the coil is hooked up properly?

The negative side of the primary should be connected to the trigger; the positive side of the primary should be connected to battery voltage.
