I'm looking into getting a high output alternator, but I have some questions. I have a '96 yukon with a 105 amp stock alternator, about 600W RMS in amps, and have plans for some offroad lights in the grill gaurd. Any clue as to what size alternator I should look at? Right now the alternator is feeling the load, no large voltage drops but there is some fluctuation on the voltmeter. Anyway, 135a, 160, 200amp ? Also do I need to replace a lot of the components such as battery etc if I upgrade the alternator?

That does not seem like a lot of a load for that 105 I would check my grounds and upgrade your battery to the yellow top deepcycle battery it will help out your rig all around, but If you insist on getting a ho alt go with atleast a 200 amp, for upgrades to audio later on

Yes, if you upgrade, go overkill.

If you can, get the maximum amps from the start. Most people are never pleased with their system a few months after they put it in. Then they want to upgrade. Then the stuff they bought will be up for sale. So if you start out with a strong alternator, you can go bigger and better later without having to worry about that part of your system.

A high output alternator will require upgrading the cable from alternator to battery, as well as your ground cable. I got a 180 amp cs130d (same housing as the original 105 amp unit) for my 97 suburban. If you really want heavy duty, go for the 144 (larger housing + internals) and it requires a slightly longer belt.

i have a 2001 tahoe, i just actually ordered a 300amp alt for it. i am going to run it parrarllel with my stock alt. the 300 amp was only like $150 more than the 200amp. if u can find a good deal just go with the bigest u can find. also later on when u sell the truck u can always sell the bigger alt easier because not that many exist. usually it has to be custom made. goodluck -------------

Hey thanks for the replies. The reason I am looking to replace my alt now is because my voltage is at about 15.2V when I start my truck and 10 mins later is at about 13-14.2. I dont get any big fluctuations on a bass hit, and I checked my grounds so I'm thinking that it's the alternator or battery. The alt. is a reman and the batt. is in question at this point. I upgraded the big 3 and the only difference it made was the voltage being at 15.2 or so at start up. After a few mins it drops right back down. Not a HUGE thing but I'm a perfectionist and it bothers me when something isn't right. Thanks again for the advice........

having your voltage steady around 13-14.2 while u have your stereo on is great. i wouldn't bother spending the money for a new alt. i don't think its gonna get better than that honestly.

Hi everyone I'm new in this forum, but not new to alternators and starters, that is what I do for living. Everything you ad to your car, CB radio, Sound System, Neon Lights, etc will need more power from your vehicle charging system, and your original alternator and battery are not prepare for that job. If any of you need a HO alternator just email and I'll get back to you with a price quoted and alternator information. ------------- HO Alternators
