I have a 1998 tc2000 with a cummins 6bta that wouldn't start. Found the issue was the starter. So I pulled it and installed a new one from napa. So I hooked everything back up and went to fire it up but had no start. This time the starter motor is working I can hear it but it is not engaging the engine. I believe the solenoid is not receiving power but cant follow the wire to find the issue. I could use some info or ideas on how to resolve this little issue. Please and Thank You!!!
