voltage gauge...possible FIRE???

[nsmall]

I am going to have my factory tach and speedo gauge rebuilt by "Redline gauges" here in SoCal.  They want $425.  Heard they are a great outfit, does that price sound reasonable?

 I have an electric fan that runs around 19 amps (I think).  Its a Spal fan, 1610 cfm.  Its a straight blade and way to loud in my opinion.  anyway, Redline gauges said the volt gauge was NOT made for the fan I'm running.  I have a stock alternator.  As for the volt gauge, they want $240 for a rebuild to handle the new electric fan. I dont have the money to have this rebuilt.  Redline gauges said I should unhook the black and red wires to the voltage gauge, and I think they said wind them together and I know they said to shrink wrap them as there is a possibility the electric fan is running to much power to the gauge on the dash and it could cause a FIRE.  Does this sound correct?  I dont mind the gauge not working as I obviously don't want a fire under my dash.  Any suggestions?

Thanks!!!!!!

For a stock amp gauge, the current is feeding through the gauge, so tieing the wires together just bypasses the gauge.  For a voltage gauge that's more typical of modern cars, tieing the wires together would create a short circuit that would include the risk of fire.  If your gauge cluster hasn't been previously modified to change from a amp meter to a volt meter, you should be fine connecting the wires as Redline suggests.

Good info on amp guage problems.

Why not divorce the fans from the dash wiring all togeather with a fan speed controller fed and fused directly off the battery.
