Car Forum / Nissan / Nissan Cars / September 20041988 PATHFINDER
Hello, Have a '88 Pathfinder SE, 5-speed. voltage gauge reads normal at idle and at steady speeds but will spike up high when accelerating or when sitting still and reving the engine. the guage never reads below normal, just high during the mentioned times and effects the speed of the ac / heater fan, which increases in speed also.. Any ideas? Thanks.. B.R. Check the voltage regulator to see if it is defective. From what you are saying I would thing that would be the problem. This is especially true if you have higher fan speed when the voltage peaks. You did not say how much it goes up. 14.2 volts is the max allowable. Also, you probably have an integrated regulator in the alternator so you might ahve some fun taking the alternator apart to get to the regulator. A regulator is pretty cheap so it is probably going to cost $25 bucks for the regulator and the time to take the old one out and install the new one. > Hello, > Have a '88 Pathfinder SE, 5-speed. voltage gauge reads normal at idle and [quoted text clipped - 5 lines] > Thanks.. > B.R. Thanks for the help, did turn out to be the voltage regulator (was running at 17 volts) :) a brush or two and some diodes were burned out as well... so, $180 to repair or $200 to replace. So, went with the whole new alternator since the difference would have been made up in labor anyway... runs great now.. might be my imagination, but seems to have a little more "pep" now.. not sure what any of the above mentioned problems effect performance.. but it does seem to run alot better now..

My reverse lights have not worked since i have had the vehicle.. bulbs are good... any ideas where to look? the horn was also working once in a while, and not at all now.. ?? more projects for me..
