Strange Electrical Issue on 95 Infiniti g20

Hey Everyone!

Anyone have any advice for me on this issue?...

I sometimes(1 in 10 drives) loose all electrical power (power steering and brakes, the clock, dome lights, everything). This happens most frequently when I'm coming to a stop or slowing down. The engine obviously dies too. The power will usually come back when I fidget w/ the battery terminals and I can start the car again. Sometimes I need only touch a terminal w/ my finger and power will come back. Rainy and cold weather make the problem appear more often. The problem doesn't seem to happen when I'm going faster than 25mph or so.

I have replaced the battery and thoroughly cleaned and tightened the terminals and the problem continues to resurface. When power is working as it should, I have tried flexing the battery cables very hard and have not been able to repeat the problem. I have also tested the battery w/ a voltmeter when the car is dead and the battery reads 12.8v. Infact, touching the voltmeter to one of the terminals seemed to return power to the car.

This is perhaps most bizarre... on a particular rainy day, electricity died several times. Although it may have been coincidence, I was twice able to get power to return the moment I slammed my hands against the steering wheel in frustration.

Thanks!

check the ground( negative) cable where it connects to the engine block

slamming hands on steering wheel gives you a clue.the problem is inside this car the infiniti g20 is the biggest peice a junk on highway.its noted for a lot of electrical problems.check plug through fire wall to ignition switch at the bottom of steering wheel colume check plug to key switch inside water is getting in some were.disconnect battery find plugs electrical connectors plug and unplug several time reconnect check water in pins or rust on connectors thats were water getting in.this car is noted for ignition switches going bad.battery proably was not bad its wiring between outside of fire wall to inside under car. look their

RoastLapan welcome to the forum, I hope you will like it here That's all I can say apart from the above excellent advice

Thanks everyone! I'll post my results here soon.

@hobbist

Great advice! But I thought the g20 was supposed to be good in it's day? Certainly giving me a lot of trouble though.

also check and see if theirs a start relay.some of these click a few relays when you turn on key.look at a wiring diagram in haynes manual.chrysler caravan dodge voyger used eclips and infiniti electrical system all had same electrical problems with key switches melting and blown alternators because key intergises the alternator and shorts it out.the elcips,infiniti.plymouth vogyer,dodge caravan all are the worst for constant electrical problem unreliable can go any were at all with out break down real junk.no to mention engine and transmission arent any good in chrysler product my intreped plymouth duster had many transmission recalls 13 all together.i will never buy another chrysler produce as long as i live their worst then the old ramblers nashes.
