Happy Saturday everyone!

Am trying to diagnose a starting problem (won't start; turning the key gives nothing; 12v coming to the ignition switch at the black/yellow wire, but nothing going out; I get a click out of the solenoid when jumping from solenoid + to solenoid S, but no crank).

Anyway... in the process of troubleshooting at the solenoid, I see this thing attached. The markings are what you can see, plus "Tung Sol 20A 12V" stamped on the back. There's a big black wire (BBW) coming out of it, not sure where it goes.

Can someone please tell me what this is? Could this be related to my starting issue...?

TIA,

20A circuit breaker, so it has to be a 12V feed for an auxiliary system. You'd probably have to trace the wire to figure out where it goes. On the upside, there's plenty of room in the engine bay, and only so many electrical connections

As far as the starting issue, do you have a voltmeter or a test light? If so, a couple quick tests can probably narrow down your issue.
