Great information! I will dig in on my 69 at some point soon to see if the fuses are the issue. I too would greatly prefer a voltmeter but if the amateur would work as good as the one in my 65 I would be perfectly happy. I can always tell right away if the charging system is functioning properly. Steve weim55 Colorado |

Re: Factory ammeters never work, why?
Does anyone know of a source for these small fuse holders? Both of mine are missing, and I would like to find replacements that are similar.

Or, for a functional but not quite as original looking replacement, you could use a couple of waterproof mini ATM fuse holders such as this: https://www.amazon.com/1st-Source-MI.../dp/B00NU9AW42 Quote:

Re: Factory ammeters never work, why?
I put one of T-Bones voltage gauge conversion kits in my truck and it works great. Link below..

That temp light gets 12V constant from the cluster and what turns it on is if that wire gets connected to ground. If you take that grounding wire and split it in two there you can connect one end to the temp switch and one to oil. Thanks, KJ

Re: Factory ammeters never work, why?
I've never had one not work. They are handy and useful for what they are meant to do.

For oil pressure, use a T right where it comes out of the block and a pressure switch from a gauge cluster car. Another thought is the bulb test when you turn the key to start.

Re: Factory ammeters never work, why?
I did that 30 year ago. Works great.

Re: Factory ammeters never work, why?
I cleaned all the grounds in my vehicle, adding 1 or 2 where necessary. The entire electrical system came to life, including the Ammeter gauge.
Use dielectric grease where you have a bolted connection. Pretty simple |

I agree, the existing TEMP light could be wired up to both temp and oil pressure switches to make it function as a "check gauges" warning light. And yes, a temp switch in the pass side head on a V8 or manifold port and oil switch connected to a Tee fitting where the gauge line goes into the block would do the trick. Wiring it up to the ignition switch (like GM did with the stock TEMP & BRAKE lights) for a bulb check during start-up is a good idea too. When I said earlier, "Adding an oil pressure light into the stock gauge cluster would take a little more work though." I was thinking along the lines of what it would take to cut in a stock looking "window" and fit it with a lens with "OIL" printed on it. |

Re: Factory ammeters never work, why?
Mine has not moved since I have owned the truck, put a fuse in the drivers side holder as there was none.
Magic.....works like a new one. Very happy. |

Re: Factory ammeters never work, why?
Of the 4 trucks the wife & I own only one Ammeter doesn't work. The wiring on that truck has been so butchered I'm surprised anything works.

Re: Factory ammeters never work, why?
Who drives around monitoring these gauges constantly?[/QUOTE]
Those who don't want to replace an engine from a severe overheat or a loss of oil pressure

Re: Factory ammeters never work, why?
Mine works great as well. Slight drop into charge territory with headlights, then gets really bouncy with a/c and gets buried with subwoofer...
