Re: IML: 60 fuel sender unit

[randalpark@xxxxxxx]

If they are still pegged after disconnecting the fuel gauge, then the 
limiter has failed. The gauges smoke because they get too hot. Some 
heat is what makes them work in the first place, as regulated by the 
sending units. Too much voltage causes them to quickly peg. For that to 
happen to all of them at the same time means that the points in the 
limiter fused.

Tom:  If the fuel sender wire was touching the car body anywhere along 
the path or at the tank, it would show full.  Did you have the 
dashpanel out of the car anytime during this process?  It sounds like a 
wire is on the wrong terminal on the back of your instruments or is 
touching something.  I would be extremely careful diagnosing and fixing 
this.  A dead short to ground on a gauge is not a good thing.  Others 
on here have warned of literally smoking their gauges under such 
conditions.  I had it happen to me with oil gauge on my 63. 
If you know how to use a DVM, get it out and check the resistance from 
each gauge wire to ground.  Remove the color coded wire that leaves the 
gauge and goes to its respective sending unit.  Test the loose fitting 
to ground.  With car cold and motor not on, the temp and oil wires 
should be pretty high; around 60-80 ohms.  With three gallons in tank, 
the fuel wire should be like 30 or 40.  The lower the ohms, the higher 
the deflection of the gauge needle.  If you are getting less than 5 
ohms on any of these, there is a short or wiring error somewhere.  If 
this is greek to you, find someone to help before applying power to 
your ignition or accessory circuit.  Contact me off list if you want 
more details.  --Tom in Tucson

Well, I got my rebuilt fuel sender for my 60 Crown back last night and 
I
just got finished installing it. Prior to the rebuild, my fuel gauge
remained on E at all times. The oil pressure gauge worked as did the
temperature and ammeter gauges. Now, after installing the rebuilt fuel
sender, the fuel gauge registers FULL even though I know there is only 
3
gallons in the tank, the temp gauge pegged at H as did the oil pressure
gauge. Anybody have any ideas what happened?
Thanx
