2002tii Amp Gauge Wiring


Recommended Posts

My recently acquired '74 tii came with what I assume are original, console mounted gauges - one for oil pressure and one for amps.  The oil pressure gauge is fine, but there were no wires connected to the amp gauge.  The back of the gauge has two studs for wiring.  Thoughts on how it should be wired?  Thanks

Both gauges are aftermarket. There were no console-mounted gauges whatsoever. And, there were no gauges for oil pressure and amperage — warning lights on the left multi-gauge handled both the oil pressure and the charging concerns.

 

Many owners, of course, added gauges!

Amp gauges require large wires (~8 GA) and are a real fire hazard if not installed properly.  A voltmeter would serve you better and not be as dangerous.

+1.  Amp gauges went obsolete in the 1950s.

International Harvester must have missed the memo, they used amp gauges up to 1980 when they stopped producing passenger vehicles. Other American cars used them well into the 70’s.

I installed VDO volt, amp, and oil pressure gauges in my '76 when I first bought the car in 1976...my first "modification".

The amp meter was totally useless....and the wiring was dangerous, so it went "into the pool".

Now I just have the voltmeter and oil pressure.

At the risk of piling on, a voltmeter is far preferable to an ammeter--it gives more useful information and is much easier to install.

PS--John76--is your oil pressure gauge mechanical or electric?  If the latter, I've never seen one with a near 360 degree needle swing.

Mike,

I went with a mechanical for that very reason...270 degree needle sweep and more accurate and easier to read than the electrics with their wide range and small needle swing. Have to install them properly and carefully. I have had no problems (leaks, etc.) in the last 45+ years. I still have the pressure sensor light on the dash...but by the time that comes on, you are < 7 psi.

That sure is a pretty polished condenser!

 

Remind me not to open my hood(s).

John,

There is a very small inconsistency in the arc of the oil light switch wire as it travels from the switch terminal to the harness sheathing. 
 

You might want to take a look at that. 
 

Sheesh.
