| alternator on an '85 auto |
Subject: alternator on an '85 auto by PLETZVET on 2009/8/16 18:43:31 My volt display started showing 11.7 in really hot weather, with A/C running while idling at traffic lights. Increased RPM's bring it up to mid/high 12's in the city, and while driving on the highway (headlights, radio and AC on) it got up to 13.9 - 14.1. Thinking that I was running on luck to get home (3 hour drive), I'm going to pull the alt and have it tested but not sure that a test can factor in the hot under-the-hood temps while under load. My question...assuming it has a factory 108 amp alternator, is there reason not to replace it with the 200 amp alternator? Although it is an old alternator - it was on the car when I purchased the car 4 years ago and was not visibly new(er) at that time. Battery replaced 2 years ago no other electrical problems noted. It might be just the internal regulator, but is it really worth putting new parts on old in this case? |
