After some troubleshooting, cleaning and re-testing, one of the two Pro Quip P1512X relays in my ARB M002 HD wiring loom is demonstrably bad. (Long story, short.... In the original configuration, I get high beams but no low. After swapping relays in the second (high) and third (low) slots, I get low beams but no high.)
These are normally open 5 pin, 12V/40A, dual 87 mini relays with diode protection. Pro Quip is (naturally) an Aussie form and their parts don't appear to be readily available here. The closest replacements I've been able to identify so far are:
- Hella 3055 (or 3082 with no diode)
- Bosch 0 332 019 109 (or 0 332 019 151 with no diode)
I'll be back in touch with ARB USA Monday, but I'd be interested to hear which specific replacement relays anyone has had success with. Manufacturer part numbers are especially encouraged.
