Should be 85 amps out of the Bosch alternator once its up to speed. The Sniper should pull around 20 amps. A pair of 14" thermos 16-22 amps (go brushless if you are limited). 10-15 amps for headlights (depending on bulbs). Ditch the wireless :lol:

Great diagnostic and switching features, cool man. See what happens when you tap the fans in. 12.2V you can live with I would think. Headlights bright enough?

I would have thought so mate unless it's on its way out anyways. I just have the std single red harmonic balancer to ac to a 1fz pulley to the alternator then water pump and back to harmonic running a belt 1430mm long.Image

I didn't have the headlights on today and running through my head what else uses power only other thing that comes to mind is the actual ac fan blower i havent tongged that yet but it may pull a few amps but nothing near the limit by the sounds.
I had to read wireless 5 times out loud before it clicked Image but in saying that I have a under seat pioneer sub amp that's going in when i power up the new kicker stereo.

Yes mate plenty of options with these.im happy with the 12.2v but I don't think the sniper is as it's flashing yellow. Will try and find more info on these, I didn't check the headlights mate but will look at that also.

Alternator should charge between 13.8 and 14.5 Volts.

Battery should read around 12.6 V on its own no load.

I'm just wondering if your battery is up to the task or it could be your alternator is on the way out ?

Mt son has an Alfa Romeo and it was doing a similar thing with low volts, turned out the battery just wasn't big enough for the load so drained quicker than what the alternator could recharge. I would consider a bigger battery if the alternator is working ok.

Hey Clint I think you can get 100 or even 120 amp commodore alternators so may be another option.

That could be part of the issue aswell having that smaller battery from a Harley which may not have enough juice to comfortably run and charge the fuel pump that's now added to the load mate.

I had a look over the alternator with a torch and found a small 40A stamped on it. I personally removed it from the inj 5.0 years back but who's to say some one didn't chuck a smaller 40a on it at some stage of its life if the oem one shit itself.
