charging issue???

[Jack Klarich]

Running

800 rpms - 12.38v

900 rpms - 12.49v

1000 rpms - 12.70v

1400 rpms - 14.38v

Are these tests made with lights or anything else on?

I would still expect to see your original 12.7 volts even @ lower RPM

You are using more battery voltage @ lower RPM than you are making

All lights on and headlight on high beam

all the eye lights on to (lights in the skull eyes)

Amp powered up

GPS on

I guess I should have turned all that off

Now it makes more sense to me:clapping:

Test it with just head lights on to see what you have

I think you should be OK now

the problem came back or actualy never left

I thought it was fixed but was wrong

Should have listen to you Jack

the voltage started dropping down to 10v again

this time I disconnected every circuit not needed to actually run

it started charging fine

I then reconnected each circuit 1 at a time

It turned oy to be the Headlight circuit

Thought it was the dimmer switch but that turned out to be OK

disconnected 1 headlight still had the issue

disconnected the other headlight and the issue went away

put the headlight back the issue came back

replaced the headlight and the issue is gone

Now at idle and with everything on it charges above 13v

the bad headlight was still working just drawing to much

Good deal Bob

Sometimes Lectricity can be a real pain

Now that you have it charging @ 13 volts you should be OK

Thanks for checking back in and good luck

PS, if you still have your old alternator now would be a good time to have it rebuilt and up the amperage
