I really hope someone can help me with this. I have a 1991 Isuzu Trooper with 2.8 liter/5 speed manual trans. I love my Isuzu! It kicks butt! The problem I am having is this... I keep going thru alternators. In the last few months, I have gone thru 3 of them. It's really starting to get frustrating. When they start to go bad, I notice a humming squeak like noise. Like the brushes are rubbing inside. Then from there, I notice my truck having more difficulty in starting from the lack of power in my battery. It is obvious that my alternator isn't proving the power to my battery to start like it should. I did replace my battery with a new one, and still the problem persists. One thing I did notice is that it is more relevant in the cold. Also, when my alternator starts to go bad, my headlights, dash lights, any light, starts to randomly dim/increase up and down. I do have fuses attached to everything powered by the battery. So to protect against surges or whatever problem may arise power wise. I am thinking that if there is a short somewhere causing my alternator to go bad, wouldn't a fuse blow? Anyhow, thank you for taking the time to listen what I have to say. If there is anyone out there who can help me with this, it would be greatly appreciated... Thanks, Tracy... |

Replying to: atfdmike (Mar 18, 2007 12:59 pm) There were a couple things I did forget to mention. When my alternators went bad, I would have them checked at my local auto store for amperage. One thing that was noticeable, is that one alternator had lover voltage compared to the other that had more voltage then the norm. I do disconnect all the wires from my battery before I add leads/grounds to my alternator. I do have a fairly nice stereo with a somewhat high power amp attached to it. Is it possible to add a higher power alternator to my truck? Tracy

Also, a bigger capacity battery might help prevent loading the alternator especially if the load is off more than on, here is a battery that will fit the Trooper battery box and has something like three times the cranking amps and and can be used in deep cycle mode without damage: http://www.lifelinebatteries.com/marineflyer.php?id=3 .. Note: Measure your battery box before ordering, I have use the Lifeline battery and an inverter to let my kids watch two movies and then the news while powering a fish aquarium every night for a week after a big ice storm. |
