Hi Everyone,
Several years ago I had a local shop install the wiring harness and switches for the ARB lockers on the '70 Bronco. There are a few electrical oddities that I'm trying to track down now.
The compressor was physically mounted by another shop prior to the electrical work being done.
I don't have the information on the compressor. I believe I bought it from someone on the forum a number of years ago. Below is a pic of it installed on the driver inner fender.
Without asking a lot of questions that I know will require more detailed information, I thought I would just ask a couple of basic electrical questions.
1. Would this ARB compressor ever be installed without a fuse and power relay? There isn't a relay in the circuit as it is now.
2. The system is wired into one of the switched circuits on the Painless harness. It is not connected to the battery and ground. This is different than I would have expected, and different than the manual states.
3. (The way this is wired now, the power wire from the Painless harness is wired to the two wires on the ARB harness that are for the light illumination power and the ignition power. To me that seems odd.)
Anyway... the main question I have is about power, and if perhaps this compressor (for locker actuation only) would ever be wired properly without the relay, and the direct connection to the battery.
Thanks,
Jeff
