Alternator options?

Hey guys i was thinking of replacing my alternator and was wondering what options are available. I want something that can handle any electrical components I add in the future.

the 4 cylinder bikes don't have an Alternator, it is a STATOR.

you need to do some tests to verify the condition of the existing charging system.

several good gurus that can help on that.

if you don't want to fix the OEM system, you can add an alternator, but it is a lot of work.

I actually already have the alternator upgrade. I just want to replace it as it looks old, and want to know the best option for overall power output

It depends on a couple of items. Do you have a three wire alternator or a one wire alternator? How is it attached - are the feet offset or straight as per:

or straight feet the top and bottom are in line:

I have the second alt installed with the top and bottom feet in line. It's from a 1988 Firefly 1.0 litre turbo and is rated at 55 amps, more than sufficient for your use. A 40 amp would also be good. My '85 LTD (fuel injected) that needs more power than your Aspencade has a max amp draw of 29 amps with the bike started, two sets of driving lights on, rad fan on, and my heated clothing plugged in. A 40 amp unit would be good as it is a bit smaller than the 55 amp unit.

From your pictures I would recommend the 1988 Pontiac Firefly 1.0 litre turbo alternator at 55 amps. You will/may have to cut the rear foot off the alternator.

You have a three wire alternator that is a good setup. The picture you show only has the excite wire attached to the alternator. You need a sense wire attached as well, an you can install an indicator light on the third terminal.

Here is a picture of the wire connections for this alternator:


Here is a picture of the indicator lamp setup:


The indicator lamp is optional, but the excite and sense wires are not.

Good luck
