Thanks everyone, I was able to squeeze under the dash and trace back all the wiring.
I installed a 6V stepdown for the radio, blower motor, sending unit, and clock. So far everything seems to be working well except the fuel gauge.
It reads 1/4 tank even though it is completely empty. Measured the sending unit and it reads 0-32 ohms. Any ideas?
Also, this may be a stupid question but I am new to these, do the front marker lights go out when you turn the headlights on? They work
with the switch halfway out, then turn off when I pull it all the way out.
Thanks,
Jim
