Re: heat at speed

[MACHWIL@aol.com]

If the instrument voltage control is faulty, BOTH the fuel and temp  gauges 
will vary with respect to voltage supplied. At idle it will read low. At  
speed, when the generator is supplying more than 12 volts, it will read high. 
On  
my 1A the I found the PO had bypassed the inst. voltage control. In testing the 
 gauges with a control the difference was quite significant. Check your  
wiring  diagram, then check the voltage control. My problem was  similar to 
yours 
on both gauges.
