Question about 1987 Nissan Pathfinder

1 Answer

I own a 1987 Nissan Pathfinder and I love the car (cant let it go) however I have run into an electrical problem. I had to replace the alternator due to my son reversing the battery cables causing a short. The car starts and the battery charges however no electrical works on the car. No headlights / brakelights / dash displays lights ect. completly dead. I have checked most fuses and everything looks good. Power does not even make it to the fuses inside the car. Finding an electrical schematic for this car has been tough online. I dont want to spend a ton on a diagnostic due to the value of the car only being so much. Am I out of luck?

There are fusible links in the electrical system. They usually are close to the battery, I don't know for sure on your car, any way they start out looking like regular wires usually 12 gauge and 10 gauge. there will be, what looks like a plastic tube molded on to it. these are the links. To check them you will need a volt meter and check voltage on both side of them. cut back the rubber coating if you have to. if the voltage is not the same replace it. you can replace them with the links, But I would get inline fuse holders and use them.

    Hi, The fuseable links are the chief suspect here, the links will have a rubbery coating and can be checked by a gentle tug from either end, ie if if stretches , it's broken, If it's solid it's sound but chech any suspected link with a meter !

I have a 91 nissan pathfinder it dies while i am driving it and wont start back up unless i charge the battery outside the car. I have gotten a new battery and alternator so i cant figure out the problem.


Once you have the engine running, place a volt meter across the battery and measure the voltage while you run the engine at about 2000 rpm. The volt meter should read in the region of 14.5 volts. If it is below 14 volts your alternator is not charging and needs attention. Also, after the battery has been used for a while and you switch the lights on, they should brighten slightly as you rev the engine, if they do not, the alternator is definitely not working.

1994 NISSAN PATHFINDER WONT START I LIKE TO FIND OUT HOW CANT I BY PASS THE MANUFACTURE SECURIETY SYSTEM . BUT I HAVE INSTALLED A AFTER MARKET ALARM AND I HAVE A BRAND NEW STARTER, ALTERNATOR , BATTERY...


First thing you should have done was check and test.NOT REPLACE PARTS.Did you test the battery to determine it needed to go? Had the starter failed to turn the engine over? The Alt supplies current to run the vehicle ,and keep the battery at the proper state of charge. How did you decide on ign wires verus the other ign components? Did it start and run okey ,before you added the after market alarm? If yes, I guess you know where some of the issues are!

I have a 1987 nissan pathfinder i cant get the front belt off the put the back one on how do i do this?


You have to get at the tensioner from underneath the vehicle. It's hard to get at. What I did was go and buy that belt too, cut the old one off and used a screwdriver to install the new one while turning the engine by hand.

1987 nissan pathfinder wont crank or anything


FIRST TRY TO SEE IF THE FUSE AND RELAY ARE FUNCTIONING PROPERLY. IF THEY CHECK OUT THEN CHECK FOR SPARK AT EACH ONE OF THE SPARK PLUGS. IF YOU ARE GETTING SPARK THEN I WOULD REPLACE THE CRANKSHAFT POSITION SENSOR. THIS DEVICE IS RESPONSIBLE FOR OPENING INJECTORS AND SPARK PULSE THROUGH THE COMPUTER. HOPE THIS HELPS. PLEASE LET ME KNOW. BEST OF LUCK
