Alternator charging way too high


Recommended Posts

hey guys I have a interesting problem! The singer altanator that I put in the truck this weekened is charging a little high, it's a 340amp alty and this thing is a beast, so much so it's bad! I'm throwing my amps into protect mode and shutting off music! Not fun! I don't know what my kicker zx2500 or kicker zx650.4 protect at but there both being thrown into protect! I've seen as high as 16.4 spike real quick but usually I spike at 15.7 and then it goes back down to 14.9!! ( this happens when I hit the gas leaving from a dead stop) or just when ever I give the engine gas in general!

Is there a simple fix?

F150 99 pick up ext cab 4.6 engine!

Singer used a gmc module on the alty with a conversion wire adapter so I could plug it into my ford harness! The thing is..... My alty had three wires( one plug with two wire and a second plug with a single wire) the singer alty has no spot for a second plug just the two wire plug! Hope that made seence!

My Mechman did this exact issue.

I switched from their AVBM module (internal regulator) to an external regulator and it fixed it.

I have no idea how it's regulated I would assume its a internal regulator within the alty itself?

Crap I was hoping you wouldn't say an external regulator was needed! That's an extra $160

Is this going to fry the actual brain of the truck or any other electronics? I ask only because if the answer is yes I'm going to remove the singer alty and throw back in the stock one for now as to not damage anything!

something needs to be done about the regulation whether that means an external or not i dont know as long as the spikes arent sustained i dont think it would damage the computer

Btw that was the first person. Ever banned by me while dropping a deuce. Feel privileged

Yeah I agree that it does need to be regulated! If that means dropping money on a external regulater than so be it!

I don't believe it is sustained because the amps do power back on after a couple seconds!

I just emailed singer! See what he recommends! He has great customer services so he should get back to me soon!

Which external regulator should I be looking at?

Also I wanted to add the big three is done but the alty is not grounded with zero gage but the alty is bolted to the engine block which is grounded with zero gage, and that ground is located 5inches away from from the alty!

Could that be a problem which is maybe complimented by the alty spiking

Hey justin thanks for calling my alty fully retarded, means a lot lol!!! Ok so how do I fix this? I mean singer used a gm case and module and doesn't allow for that stator lead to be connected! It's just hanging off to the side!

Does this mean that indeed I will need a external regulator to keep this alty in line?
