mixing alternator brands and styles


Recommended Posts

Posted

I currently have a 2002 Tahoe with the 5.3 v8 motor and I'm running a mechman 270a alt on it, well a friend has a 2007+ avalanche and has 2 dc 250a alts he's about to sell, I believe his avalanche is also the 5.3 but with the year difference, if I got a triple alt bracket could I run all 3 alts together if I leave my mechman in the main spot and used the 2 from my friend in the 2nd and 3rd spot sense it would just be getting cut on via the 12 volt wire in the harness?

Please let me know if this will work or not and anything else I should know related to this subject, thanks!

Trying to guess the SPL of a system with out a meter is like trying to guess how much air pressure is in a compressor tank just by letting some of the air out.

...Seems like 90 psi...

My theory is that it should work if you can get all the voltage regulators set to the exact same voltage. Maybe external regulators would help, not sure.

CURRENT SYSTEM:

  • Alternator:
    1. Stock alt on mids/highs
    2. Isolated DC Power 270 SP - Charging @ 16.8v
  • Batteries: (2) XS D1400s
  • Power Cable: Double Runs of 1/0 KNU Kolossus Fleks
  • Headunit: 80-PRS
  • Sub Amp: DC 5.0k
  • Subwoofers: 2 RE MT 15s /PSI dual .7ohm recones
  • Subwoofer Enclosure: 9.1cubes @ 32hz - brutal.
  • Mids & Highs Amp: CT125.4
  • Active Components:
    • Mids RE XXX 6.5c
    • Highs - 3 RE XXX tweeters per side(A pillar)

this will work....just tap into the wire coming out of your factory plug that is in the "L" spot. That wire is the one that excites the alts and tells them to start charging. the voltage regulator with the highest voltage should take over

will work just fine.

chances are his gm alts are the same as your gm alts as well, maybe just slight cosmetic differences in the cases, and possibly color options.

Just make sure to link all 3 alternators together with 1/0 so they will all see the same load at the same time.

I ran a stock alt for a few years while I waited to get that 3rd dc power 390xp under my hood.

Only issue I see would be voltage. My mechmans charged at 14.4 but my DCs at 14.8

Tell me...does this smell like chloroform to you?
