I have a 1993 Maxima (SOHC, Automatic). Just recently (about two weeks), I've been having these bizarre electrical problems with my car. I wake up to my radio stations cleared, my clock at 12:00, power locks not working & seat belt not moving in position when the door closes or opens. The car starts up with no problem and then everything starts to work again. While driving, my dash lights would cut off as if the juice was being momentarily taking away. The radio turns off for a split second every time I tap my brake causing my antenna to retract then go back up. When the turn signal is activated, the light stays frozen for a second or two and then starts to blink as its supposed to. This progressively has gotten worse. When the radio is off (because it constantly shutting off is extremely annoying) I can hear my speakers make a revving noise as I step on the gas pedal. The seat belt light in the dash is constantly flickering. Now when I turn the ignition switch to the off position, the car has no juice. If the engine is not running, the car goes "limp"...nothing works electrically. The power locks don't work, the seat belt keeps you strapped in when you're ready to get out & the dash, dome, hazards, radio, etc. don't work. The solution is probably something simple like reestablishing a ground wire but I'm at a loss. This problem is a real pain...but I would hate to put this car on neutral and rolling it off a cliff. If any electrical gurus out there have a solution, it would be much appreciated.

 

check your battery cables and terminals for corrosion and wear
make sure the cables are snug on the post, it sounds like a bad/loose connection somewhere in the main power wiring (or ground).

 

constant-battery-powered fusible link at your battery.. clean/inspect/replace.

 

Mee too, 93, VG30E... Luki here, one hidden nissan problem place related to mentioned batt problems, under the battery tray.:


I suspect your view there is smtg else; here its all cleaned, closed...





Checkout your charge voltage att batt. If its under 13.8V while idling, problem is bad alt and/or floating ground. Adding one gnd wire will hlp (grn/yel wire). Clean connectors first...
