Another integra and electrical problems.

I just purchased another integra. I didn’t notice it until a few days after. My radio and dash clock always resets after turning off the ignition, and also when turning my fan to full blast my radio starts to shut off and turn back on repeatedly. On the lower speeds its ohkay. I dont even know where to begin. Please Help!!!

id also like to know my clock would always reset when i shut it off. but now it doesnt do it i did nothing to fix it either

the radio/back up fuse under hood allows constant power to the pcm, radio and clock for memory, IIRC. but that is just what i recall from a g3 diagram. though it’s probably the same for g2. it sounds like that circuit may have a poor ground. you could check the current draw of that circuit with ignition off, as it should be hot at all times. if it’s a poor ground, it’s going to draw less than it should, if any. you can use a 12v test light to see if it’s drawing power at all

on second thought, the amount of current that it should be drawing wouldn’t be enough to light the test light. since it should be less than .05amps. you’ll need to use a multimeter to probe the circuit.

Fuse for radio back-up is in the under dash fuse box on G2s and most likely the problem.94
