I have a 79 MX32 and am having the weirdest electrical issues. I have no power to my gauges, blower motor, or rear defog; but my wipers, radio and all lights work. I have 12 volts to all fuses at the fuse box and I have replaced the ignition switch. Charge light is lit VERY dimly. Alternator checks out at 14.2 volts running and battery is new (12.4 volts with engine off). Any ideas?
