Re: How to tell if it's charging?

Dell, that assumes the ammeter is wired properly. If the wire is going through the loop the wrong direction, the gauge will read plus when it should be minus and vice versa. I want to verify that it is doing the right thing before I trust that gauge.

Besides, it's barely off zero...

I've got a couple of analog meters I'll try. One is the $10 cheapie and the other is on my $90 battery load tester. That one's easier to use with the nice big cables and clamps...

" If the wire is going through the loop the wrong direction, the gauge will read plus when it should be minus and vice versa. "

Huh?

It's a loop.

It can't go in the wrong direction because the ends of the wire are still attached to the correct terminals. The wire goes from point A thru the loop on the ammeter to point B.

How could that possibly read backwards?

Pretty sure (I have 3 or 4 of em) that you can go thru the loop the wrong way.

Maybe I'm having a CRS moment.

On an 8N, point A is the solenoid. Point B is the terminal block. The wire goes from the solenoid through the loop on the meter to the terminal block. Or, vice-versa.....doesn't matter.

How can it go through the loop backwards?

CRS moment?!

The current flows one way, the needle deflects one way, if the current reverses, the needle deflects the other way. Maybe I'm wrong but I know I've reversed it on a 9N.

Well yea, if you reverse the current (as old said) it will read backwards.

But if it's a loop meter & one end of the wire is on the terminal block & the other is on the solenoid, it's not 'reversible'!

On a 9N.....it goes to the hot side of the starter switch, right?

Sorry been away from the computer a couple of hours. It goes from the hot side of the starter switch thru the amp meter to the hot terminal on the resistor block. If you re wire it so it goes from right to left instead of left to right (thru the loop)it will be reversed.

Bruce if you think about it for a moment you would see that he probably has the battery wired back wards as in - ground so yep the amp gauge would in fact read back wards. My Oliver 77 is that way and has been since I got ti but I know the alternator works just fine so I have not changed it since I know it is wired back wards so his tractor probably has the same problem
