Question. Working on a '93 accord with main relay problem. Relay is not pulling in and I diagnosed it to a bad ground. When I jumper black wire to ground car fires right up. Does anyone know where this wire is grounded? Links to wiring diagrams?

Thanks.

 

Main relay's black wire is routed and grounded at G101, located on the thermostat housing.

 

Thank you! I'll check it out.

 

That was it. Bolt was loose.

 

That one loose bolt can cause a host of confusing electrical problems. Glad it was an easy fix.
