volt meter,amp meter

Postby flojo » Fri Mar 28, 2014 5:17 pm



HI, installed in the left side of the fairing of my 86 aspencade are volt and amp meters. Can someone tell me what
I am looking for when I look at these things? I am having some battery/charging problems and need to start watching this stuff.

also, the 3 yellow wire connector looks funky-(pic attached) can this be causing the battery to not recharge properly when the bike is being ridden?

Ive read the posts on how to repair this , I just want to confirm that this is bad enough to cause a charging problem

Quickly chop that connector off and solder the wires direct.
As far as volts.If it measures the battery and not the switched power,Expect to see 12.8 minimum at 900 rpm and peaking at 14.5 at 3500 rpm.
Amps...again,depending on where its being measured.
Charge rate to the battery should peak at 15 amps right after cranking and then taper off to 3-4 amp within 10 minutes of running.
The charging system is capable of producing about 25 amp max at 3500 rpm.
If the volt meter is wired into the switched ignition line,the voltages can be as much as 1.5 volts lower than the battery.

Thanks Virgil-I shall chop. I think I read somewhere that it really doesn't matter which upper yellow wire gets soldered to which lower yellow wire--Is that true?

thanks

It is true any upper to any lower will work just fine, make sure you have good clean wire to solder to and use GOOD quality double wall shrink tube to insulate them. Tape alone will not be enough. 8-)

While your there,I'm most concerned about the amp meter.
If its a clamp over wire sensor block on the charging wire its fine.If its hard wired by cutting a wire and hooking the amp meter in line ....it better be using a #10 wire to the meter.
Take some pictures of the wiring and meters if you can.

Hi, before you solder the wires together check the voltage from your stator you should have 70 plus vac across all phases make sure your meter is on ac not dc, also if one phase has a lower voltage this maybe not a good sign you may want to do an ohms test across the phases should show 0 on a analog meter! If you get reading more than 0 you have a short and your stator maybe toast, I had his problem with my 85 gw and did the alternator conversion never looked back lots of voltage and amps and is working just fine after 15000 kilometres

I am not a mechanic but the conversion was a lot easier to do than pull the motor out
