bigred48 Posted August 27, 2007 Report Posted August 27, 2007 When i fixed my horn I needed to pull the ammeter, it had not been reading very high amperage and decided to test it and it would not read. Does anyone know where I could find a new ammeter. Or can i buy a universal and then use the face to the one I have. Thanks Quote
steveplym Posted August 27, 2007 Report Posted August 27, 2007 Sometimes you see NOS ones on ebay. Another forum member may have one. You can use a universal one if you like, not sure how you would combine new with the old though. Quote
Young Ed Posted August 27, 2007 Report Posted August 27, 2007 I think I have whats probably a good used one? Quote

The reason your ammeter did not read very high amperage is because your battery is most likely close to being fully charged. An ammeter reads the flow of amps or in common terms the flow of current. It does not read voltage. A high reading on your ammeter indicates a low battery condition or a malfunction of your voltage regulator. How did you test your ammeter? Quote
Norm's Coupe Posted August 27, 2007 Report Posted August 27, 2007 Don is right. If the amp meter is reading 0 or just a little over, it sounds like your battery and charging system is in good shape. Usually, the amp meter will read a little higher immediately after start up, then settle back to the 0 or slightly above 0, unless something is wrong. If you amp meter was reading high before you fixed the horn, the horn was probably draining the battery, causing the charging system to compensate and give you a higher reading on the amp meter. Since you fixed that problem, the charging system doesn't have to overwork itself, thus now the meter will not show a high reading. Quote
Lou Earle Posted August 27, 2007 Report Posted August 27, 2007 Test: pull your light switch on and off watching the gage- engine off- needle should move to neg side a little with parking lights on more when headlights come on- then hit dimmer switch -needle should move. Final test leave lights on 10 15 minutes and then crank car should show healthy charge. At least that is the way I test them Lou Quote
