Question about 1998 Mazda 626

1 Answer

Electrical fault I was fitting driving lights to my 98 GF 626 and whilst fiddling with the fuse box to pick up a power source I heard a series of clicking noises like a relay or something operating,then it stopped, leaving me with no power at that particular junction and no central locking, no radio, no intertor light and the engine seems harder to start and has a high pitched whine in it while running which was not there before. Any ideas what I might have damaged in the electrics please. regards

    Thanks for your support, My Mazda does not have central locking in the boot, it is a hatch. Sounds like it could be the ECU unit behind the fuse box. Would this be causing the other symptoms as well. Regards

    Hi Jean. I have the fuse box out of the thing but I am not sure what the ECU looks like. If I can Indentify it can I easily test it. I noticed a big black box hangig down under the right hand side of dash about the size of a DVD case. Is this the ECU or would it have something to do with the aftermarket alarm system fitted. Regards Malcolm

Malsmed,

Does your mazda have a central locking unit in the boot? If so then follow the wiring if you can to the fuse block and see where the wiring goes into and check the problem their? If that does not solve the then check the central locking unit in the boot and the ECU unit behind the fuse box.

Hope this will help you

Please make sure earth/ground points are tight and free of dirt and corrosion. especially knowing this is off road car. fuses are clean. charge relay is working correctly, main fuse CONNECTIONS are good. the fact that it happens when you move , means most likely a loose connection.

I HAVE A MAZDA 626 98 AMERICAN MODEL WITH BRAINBOX NUMBER F82F-12A650-GF. THE BRAINBOX IS DAMAGED AND I HAVE LOOKED EVERY WHERE WITHOUT SUCCESS OF REPLACING THE BRAINBOX WITH THE SAME NUMBER. CAN U HELP...


Majority problem on the ECU is the leaky electrolytic capacitors.
If you has the time to do soldering then you can fix the brain box for under $15 vs $120+ for a use one.
Just open the cover and look for damage (over-heated + leaked) capacitors.

Hi I inherited a 1991 mazda 626 which is not in very good condition. The latest problem is that whilst driving along, all the lights on the dash light up eg, brake,door, etc and the car just dies. Any...


This sounds to be a Body control module. The first thing to do is pull all of the fuses one at a time check to see that they are good and reinsert them. what this is doing, besides making sure the fuse is good, is making sure every fuse has a good contact. Check the relays also. I have fixed many electrical problems by just pulling the fuse and reinsert it. same with the electrical plugs. When pulling plugs always check both ends for corrosion.

I am trying to replace the small lights that illuminate the rear license plate. Can you tell me the best way to get them in and out? Where can I find the fuse box? I have a 98 Mazda 626, thanks!


if it is situated in the bumper, you just take a flat (thin) screwdriver and lift the lens, then replace the bulps and press the lens back on

No rear side lights or no plate light on my nissan navara 2008 pick up


any time two or more electircal gadgets die together a common item, such as a fuse, is to be checked. in your case seems the light circuit, excluding the headlights, has a fault. if the fuse blows again i would examine the wiring harness, especially to the rear lights, for damage and then each of the light sockets for dampness. if no fault is found, i would replace the light switch relay and then the switch itself.

Electrical fault somewhere


Hi,
I think the problem is not the alternator but the conection in the 120Amp fuse to the main engine fuse box.
The actual contacts to the spade fuse are enclosed and the contact area cannot be cleaned (scraped) easily. The fuse does not pull out like the rest but is bolted in with two bolts (one 8mm and one 10mm) No one knows this at first, release the bolts on either side and work the spade fuse up and down many times to score the contact area.
When I first tested it it was showing some 20 ohms with a high impedance meter but after it was cleaned it showed close enough to zero.
The high resistance connection on the 120Amp fuse may have caused a volt drop (with all systems on ie engine, air, wipers, and headlights) sufficient to drop out the engine relay and it conk it out. It starts again readily but the low voltage may cause the stop light warning light to come on.
Volvo had the car for two weeks and couln't fault it after I did the clean and replaced the engine relay - but they didn't charge me - so good on them. They quoted me $1400 to fit a new alternator saying they had seen the problem before and they replaced the alternator and the cable which may have inadvertantly fixed the bad connection on the 120Amp fuse.
I worked for Volvo Truck for a couple of years as a contract Production Engineer but when sales went down I was moved on - guess I was too much of a smart arse. Renault owns them now - predictable I should have thought.

This is an electrical fault. There is a partial contact in your fuse box. Take your car for diagnosis.
