OK it is SOLENOID.
The function of the ignition solenoid is to pass power through when the ignition is on.
One large lug (the "IN") should read chassis battery voltage at all times.
The other large lug (the "OUT") should read the same chassis battery voltage when the ignition is ON.
There will be either one or two small terminals.
If two, one is ground. If one, the solenoid grounds by metal to metal contact from the solenoid body to chassis ground. The other terminal receives a 12 VDC positive signal from the ignition switch when it is turned on.
What voltage do you read at the ignition solenoid:
Small terminal from ignition switch with ignition ON
OUT lug with ignition OFF and then with it ON.
