monitoring an airhead charging system

I have a 1975 R90/6 that I recently picked up and was wondering what is the best way of monitoring the changring system since I run heated gear in the winter. Would a volt meter or ammeter be the better method of monitoring the charge-discharge state of the charging system to help prevent the battery running down due to excessive draw when I crank up the heated gear? Its not so much a problem when I can keep the rev's above 4K, but if stuck in a lot of stop and go the charging system is probably falling shy of the draw, and having a gauge indicating dis-change to remind me to say, turn off the pants or otherwise reduce the draw when I'm not able to keep the rev's up at a more constant rate.

While I do plan of upgrading the charging system, that probably won't happen this winter so I need a way to monitor the current draw.

Any thoughts?

Thanks

RM

Kisan makes a charging monitor, the CG-25, that has an Ammeter, Voltmeter, and Temp display. Pricey but great product. I have one on my 93GS.

You could also convert your turn signals and taillight to LEDs to save quite a bit of juice. Motoelekt.com makes the Beacon LED taillight for your bike and Kisan offers a great electronic flasher relay that supports LED turn signals. I think I saved close to an Amp at idle with my LED mods. Look for my "Airhead LED pr0n" thread in Airheads for info if you think you want to try this.

P.S. (You'll get more responses to Airhead questions in the "Airheads" subforum.)

A voltmeter will tell you everything you need to know about your electrical/charging system.

I agree with ignatz72.......................LED lights will save amps that are then available for other loads. Another amp savings is to use a lower wattage headlight.

I put one of these in my G/S dash:

Very inconspicuous (just a single multicolor LED) and it gives me a clear indication when I'm not in the 'charge' zone or if something was to go amiss with charging circuits.
