Disabling 1966 B Body Ammeter


There's been some talk over the years how the ammeters in the Pontiacs are a fire hazard. They run live current, unfused and apparently can occasionally cause a fire, or maybe even just a melted harness if you're lucky. I've been especially nervous about it in the last few years since I bought my Strato Chief and have been reading more about it.

Earlier this week at our CP coffee night I mentioned to a couple of guys that I had removed the wires from my ammeter since I put my car away for the winter. I had been wondering what to do so I would know the charging system is working, and I saw what I thought was a neat idea on a car forum a few weeks back. I searched online and found what the guys discussed, a voltmeter that plugs into the lighter. The bonus is, it's also a thermometer and and ammeter. The ultra bonus is it has 2 USB ports in it as well. By the way, don't be in a hurry. It took about 7 weeks from China!

It arrived to day in the mail, so as promised by me to someone on Tuesday ( I forget who it was!), here's a picture of what I bought.

I plan to wire my lighter socket through a relay (without chopping up my original wiring harness) so the socket is live with the key. That way I won't have to always remove this thing when I park the car.

Here it is in my truck power socket with the truck not running. Ignore the fuzzy images, the digits are crystal clear on the meter.

Neat gizmo Carl. I see them on Amazon but they are more expensive. I guess the only benefit of getting one on Amazon is you'd have it in a couple of days

I haven't heard of this issue for GM cars, but I have for Mopars.  My understanding is that it's typically due to a bad connection at the bulkhead connector (at the firewall) caused by corrosion or otherwise.   I've seen people rewire and install a voltmeter in place of the ammeter, but I've also heard that you can alleviate the situation (on Mopars) but simply taking apart the bulkhead connector and checking/cleaning the contacts, then greasing and reinstalling.

Where does the issue occur on Pontiacs?  I'd like to know in the event that I actually get one of these some day...

Looks like an economical method to monitor your charging system. Carl, when you disabled your ammeter, where exactly did you remove the wires?

It's a very good idea Carl, and the USB is very useful. The one negative I see is that glowing red display. I'd not want it in my face all the time. I suppose you could apply a little strip of dark window tint across it? Or just use it as required.

Like Todd linked, there are many good choices on Amazon.ca/Prime. And some well priced with a get to your door next day.

So far I unhooked the wire from one side which goes to the big red wire at the horn relay. I plan to unhook the other side which goes to the cable at the starter the next time I work on the car. I had someone tell me that my charging system won't work if I don't put a jumper wire across the connector that is on the back of the ammeter. I haven't looked at the wring diagram yet to see if I can figure out if that is true. I will likely just try it unplugged and see if it charges. If not I'll have to put a jumper wire in the connector and try it that way. Either way, I will have eliminated the source of fires.

I drive it so little in the dark I don't think it will be an issue but if I do find it too bright I'll just unplug it for that time.

Would you be able to achieve the same degree of safety if you put a fusible link in line with the ammeter?  Then you could have the best of both worlds...

Thanks for posting that Carl. I was the one asking about it. Would work great in my camper to keep an eye on the battery levels when we are not plugged in. I kinda like the one Todd linked, as it shows temperature and voltage at the same time. Food for thought for spring time.

My car has been converted to an alternator at some point and on recollection, I have two wires that join into one near the firewall and then that wire I believe goes to my ammeter (which is now a volt meter I guess).   The single wire goes into the firewall and I have not traced it to see where it actually goes but I believe it goes to the meter. 

Anyways, once I accidently separated the two wires as the wires have a nice plug and I somehow leaned on it and separated the wires.  Of course the ammeter (voltmeter) did not work but I noticed that my battery was almost dead as I had my lights on, so they were drawing current out.  I plugged the wires back in and the meter worked and showed the system charging but I strongly thought at the time that my system ceased to charge when the wires were separated, but I could not prove my theory and I didn't think much more about it.  Funny, but I also had this suspicion of the system not charging when the meter was disconnected.

So, I ordered one of these cheap 4 in one plug in volt meters yesterday, for that price, I can wait 6 weeks.

This one rotates, a few seconds for volts, then a few for temp, then a few for amps. But yes, the idea of both at the same time is kind of cool too.
