Hey all, I am seeking advice on identifying the cause of an electrical draw on the battery in my 1993 80 series LC.
Here is what I've done so far:
I feel like I am running out of ideas on how to fix this issue. I plan on testing the relays tomorrow, but I would also appreciate any tips and leads on things I should look at or try.
TIA!
Here is what I've done so far:
- I bought a new AGM battery from Costco
- The previous battery was ~7 yo
- I cleaned up all of the engine ground wires and other ground wires I could find
- Installed a new started (reman)
- I tested the old one before I replaced it and the test showed it was still "operational"
- I cleaned up the leads before connecting
- Checked all fuses and replaced two
- Repaired some wiring from the PO near the oil pressure sender unit
- No remote start, alarm system, aftermarket lights, or aftermarket stereo.
- I've looked at as much of the wiring harness as I could access. The only thing I've seen that was out of place was some weird incision from the previous owner near the oil pressure send unit (passenger side).
- I replaced the alternator two years ago with a new 80 amp unit from rockauto
I feel like I am running out of ideas on how to fix this issue. I plan on testing the relays tomorrow, but I would also appreciate any tips and leads on things I should look at or try.
TIA!
