Chance_P Posted September 23, 2013 Report Share Posted September 23, 2013 My jeep has a factory 117a alternator. Denso externally regulated small case. I can buy a bolt in large case denso 160 amp for 50 bucks. Anyone think its worth it? Its not a rebuilt alt, just a factory denso alternator with half the miles my 117a has on it. The 160 has a larger pulley so I will swap the smaller one from my 117a onto it. Ive got plenty of belt wrap to prevent slippage. Im running a hifonics zrx2000 and a soundstream picasso nano 520.4. Does this sound like a good idea or a waste of effort? Link to comment Share on other sites More sharing options...
SnowDrifter Posted September 23, 2013 Report Share Posted September 23, 2013 Shoot for 50 bucks might as well give it a try. Just save your original stock alt. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
graham0599 Posted September 23, 2013 Report Share Posted September 23, 2013 It can't hurt to do. Especially at that price. How much voltage drop do you have currently though?

Chance_P Posted September 23, 2013 Author Report Share Posted September 23, 2013 Voltage drop is pretty bad after I removed my second battery. Probably down to 13.0 while driving. I have a cheap battery up front but im replacing it with a rebadged deka intimidator from oriellys on friday. Link to comment Share on other sites More sharing options...
graham0599 Posted September 23, 2013 Report Share Posted September 23, 2013 Then I would do the alt.

Chance_P Posted September 24, 2013 Author Report Share Posted September 24, 2013 I wish I could have gotten some before and after readings but my multimeter decided it wanted to commit suicide. Ive never felt wires get so hot lol. Pretty sure it has to do with my friend using it to test current draw the other day.. but anyways. I can't believe the difference installing that alt made. Zero voltage drop while driving and my volt gauge (factory innacurate pos) doesnt drop below 13v at 700rpm idle with headlights on. It used to hit 11.8-12 with my lights off. My system really woke up also. I thought I was getting used to everything because it was a bit quieter but now its back to what it used to be. Can't wait to get some numbers at the midwest spl event this saturday! It'll be my first time at an event. Link to comment Share on other sites More sharing options...
Chance_P Posted September 24, 2013 Author Report Share Posted September 24, 2013 Pretty sure my factory alt was on its last leg. My Jeep fires up so much faster now which I found odd. I've got to install an anl fuse tomorrow because I lost my fuseable link between the alt and pdc when I did my big three with 2/0. I normally fuse to what the wire can handle but since its just from the alt to the pdc and my alt is only 160, should I just stick a 200amp fuse in there to be on the safe side?
