I’ve already put an ohm meter on it and it’s an open circuit and I’ve tried tracing the wire but you don’t have access to all of it and most is wrapped tight. I can run a fused circuit from the battery but prefer to find the problem. Let’s say the power originates on the motor solenoid which is common and the break is somewhere in the harness if I run a new circuit the original break could cause me problems. I’m a retired electrical engineer so I’m familiar with wiring but frustrated due to the lack of a wiring diagram.
