Hi all, I am in need of some help. I suspect what little brain power I had is leaking out of my head as I get older...
I have a 95 LWB, NAS here in Texas. The truck has been pretty well cared for by the PO's.
A couple of weeks ago, with no discernable cause, the battery died. Checked it, and it looked like a cheapo replacement but was only about six months old. No problem, ran out and grabbed a good quality batt and all was well...
For a few days. Then the brand new, high end battery croaked. So, alternator, right? No problem. The one on the RRC was the original Marelli I believe, so I ordered a direct replacement (got a UK manufactured Denso in a Marelli box for some reason).
Figured I could do worse than Nippon Denso for an alternator, so I threw it in there. So at this point, charging system checks out, battery is great, all is well.
Except for the continuous drain on the battery while sitting. So, I re-check the charging system and am getting what I should there. My good multimeter has been misplaced or stolen, so I ran and got a cheapie at Home Depot last night. It only measures Volts and Ohms. With my neighbor's help, I completely disconnected the battery terminals and then started pulling fuses from the engine bay block looking for resistance across. All were fine except four out of six of the large (maxi?) fuses for ALTERNATOR (100a), HTR/ACON/AIR SUSP (60a), W-LIFT/CDL/SEATS/ROOF (60a), and ABS PUMP (30a).
I used the search feature and couldn't find anyone having the same issue, so I decided to post. Please forgive me if I didn't search well enough.
Anyway, I am thinking there could be a relay behind this, any suggestions?
Thanks from miserably cold South Texas!
