I'm workin on a 1994 Honda Passport.. HAd some wierd electrical problems... they all started when I was rolling down the highway in a rainstorm at night and literally turned on every electrical device in the vehicle.. I noticed my battery was draining.... I saw the post that suggests a poor connection... I have not installed a new Alternator... I used a volt meter and measured the installed battery at 12.25 and as soon as I start the car... with nothing on just the motor running the battery measures 11.6 volts... with the car running the alternator should provide about 13 to 14 volts at the battery... in other words, the alternator should run the car, and provide a boost back to the battery. I'm thinking my alternator isnt kciking back the 14 volts to the battery that it should. Any comments appreciated. Unclwayne.

I agree with your diagnosis. It's likely either a bad connection or a faulty alternator. But there is a third possibility: the battery is old and cannot adequately take a charge.

#16 of 111 1994 Honda Passport Fuel pump wiring problem? by mysticbuck

Mar 06, 2008 (7:05 pm)

Driving down the road Honda just quits. It will crank but wont start. Took it to the local repair shop and they said that it had something to deal with the wiring from the fuse to the fuel pump itself. They said the fuel pump was ok its just the wiring that's bad. Also when they had it on the hoist and had it connected to the computer it would run fine, but once off it would just quit. Anyone have any idea on what this could be or if something else could cause this type of problem? Also does anyone know where the wires run and where i could possibly get a wiring diagram? Any assistance would be greatly appreciated.

I have a 1997 Isuzu Rodeo V6 which is the same as honda passport. I have an issue very similar with the fan blower not working and the brake and battery light on. Alternator was replaced...still not charging..battery tested ok....I was advised to use a factory alternator instead of OE reman. I have one on order as of 3/29/08. I hope this is the solution otherwise I have been told to look to the PCM (power control module) for the problem!

I have a 1996 Honda passport and have noticed that the alternator and or battery is the suspected electrical problems in most Honda Passports and you should loosen the alternator; then make sure the electrical plug is properly and tightly plunged into the alternator.
If this doesn't help go to auto zone and they will check your alternator for free.
\You may notice the radio cutting off intermittently and many other strange things happening to your Honda passport or Isuzu Rodeo. I hope this helps.

As I have stated in nearly every instance like this...Not to knock Advance Auto and/or Auto Zone...but unless either one can give you an original new factory alternator, you will continue to have these problems. Whatever reason in the reman's the voltage regulators are no good. The blower for the fan is grounded to the engine control module via the voltage regulator. And if the voltage regulator is bad... well there you have it. A reman alternator will test great at about 15 on the bench, however if you test the same alternator while it is in the vehicle, it will show as bad!

#20 of 111 AUDIO PROBLEMS??? INSIGHT PLEASE!!! by ufchamp87

Apr 25, 2008 (11:00 pm)

Ok so my 95 Honda passport runs great, just 2problems! 1. When driving for moderately long distances (c30 miles) or so the check engine light comes on, it's not steady though it shuts off if i am not accelerating however every time i accelerate above approximately 10MPH the check engine light returns and usually stays on until i take my foot off the gas for after about 5 seconds....any ideas? 2nd concerning my radio (original stock) only the passenger side front speaker plays audio constantly and the other speakers seem to respond with clips of intermittent audio when traveling over hard bumps or the volume is turned up loud and even then speakers only respond intermittently? And suggestions?
 
Any insight is greatly appreciated, thanks NUR

#21 of 111 Strange Electrical Problem by msmith2156

I have a 94 Passport. This all started after having new tires put on front. The Rear Anti Lock Light came on as did the brake and check engine lights. Temp guage went full hot, Radio quit, Blinkers Quit. Thought I had thrown a belt, got out checked under hood all OK shut the hood got back in and all lights were normal heat guage came back to normal and ran fine. The next day it happened again and again went away. I did find one ground connection bad as well as the positive terminal connector on the battery. changed both, Problem solved, until I started home from work, and it all happened again. It kept it up all the way home off and on.
 
Who knows what this could be?

Turned out to be a faulty ground located on the Firewall directly behind the engine. Connections were Red Hot and melting down the plastic. Took the factory clip thing off put connectors on the wires and attached directly to the firewall. All problems solved. Runs like a dream once again.
