after changing the 15 amp fuse in the kick box 2 seconds later after the wipers started to work it blows up...

story so far :
My mechanic did service on my gto and installed DOT lights.
After i got the car my dash did not light up at night, both rear/front windshield wipers did not work. I looked at the kick box and 15 amp fuse was blown, i changed it then it blows up again..

you have short somewhere, it must be something that the mechanic has done!

:thumbsup: a fuse is a safaty device to protect again wiring short circuit but also protect current overload. why the fuse can blow off, is because no resistant and cause current over flow. i think is likly, after adding the dot light it cause current draw over loaded. othewise the fuse will immdiate blow off if there is a wire short citcuit. the simplw way is 2 change a bigger fuse.

:thumbsup: total= DOT light watt / 14v = X amp, u needs 2 increase 4 your 15amp fuse. so maybe the next is 20 amp fuse.

:thumbsup: if after changing the bigger fuse yet blow off than is possible your wipper motor coil short circuit. that u got 2 change your wipper motor

:57:
.

apperantly my mechanic wired the dot lights thru my windshield motor :) , this is what he wrote.

"
The Daytime running lights are wired through the wipers, if you have a look at the wiper motor under the hood on the right rear of the engine compartment, there is a wire that runs to the light that is on the hood. I connected a wire from the wipers to this light - try cutting the joint that i put in and see if this makes a difference. It may be possible that you have a shorted light bulb causing too much resistance"

NEVER EVER put a larger fuse then what is supposed to be there. EVER, that is the dumbest information I have ever heard.

I have worked for an electrical contractor and people have been fired on the spot for doing that... **** THATS STUPID. Hey lets add a higher amp fuse on this 18 gauge wire so instead of the fuse blowing we melt our **** wires.

If you are blowing the fuse than that means you have a short somewhere. Or the power wire has bare wire exposed and it is grounding out before it hits the item is is susposed to be powering.

Never hear b 4, when the wiring shorth circuit a fuse still can hole for 2sec after wipper started.

Any expert member can help to explain why.

Automotive wiring catch fire only when you don't add fuse in between 4 protection. To add a bigger rating fuse is not a "'DUMBEST INFO or STUPID IDEA"

If really your wiring short circuit, even you add the rating up to 30amp, the fuse were still can blow off.

Common knowladge: any power short circuit in your car wiring, the fuse blow off immediately you switch on the power. That is no such thing the wipper still can operate for about 2sec than the fuse blow off.

By adding a bigger rating fuse r just do a common testing on the power over loading. if after adding the bigger rating fuse n everthing is working properly, which mean in actul fact there is no short circuit.

Common knowladge: Too much sharing with 1 power sourch will causer overload.

The most common wire for car , can at least endure up to 30amp not melt. only 2 factor to cause the wire 4 melting.

1) No safety fuse is added, when short circuit, the wiring were melt cause by heat build up rapidly. (Catch Fire).
2) too low wire gauge but high current flow. under Long hours of overloaded will cause heat slowly build up during current flow, eventually, heat melt the wire. but that will take you sometime. (Correct wire gauge were not melt) Common happen in your HI-FI sets, when the wire is under gauge and yet you fit a high power capacity in before the safety fuse.

The problem is the gauge of wire used in that system. If the wiring is not rated at 30 amps, then putting a 30 amp fuse in can be dangerous and can cause the wires to melt before the fuse even pops.

Your best bet, to find out where the short in the system is, is to unplug one item at a time that is attached to that fuse. When the fuse stops popping, you have your source of the short. Find the shorted wire and repair. Since your mechanic recently did some wiring, just unplug what he had done and test. If you have no short, take it back to him to have him fix his mistake. A couple of new lights should not make a 15 amp fuse blow.

so ill put the fuse idea a side for now, but can someone please tell me if this makes a difference ? because my mechanic wired my dot lights thru my windshield wiper motor

"The Daytime running lights are wired through the wipers, if you have a look at the wiper motor under the hood on the right rear of the engine compartment, there is a wire that runs to the light that is on the hood.

Sounds like he spliced in the daytime running lights to your hood light???

What he should have done was to put it on a seperate relay and made it's own fusible link off of the battery. I would have someone else wire up the lights if you aren't electrically savvy

+1 but be sure to make sure you don't have a constant hot for the DRL's and it is on the ignition so that the lights only come on with the car.

k, i cut the wire that my mechanic spliced the DOT lights into, it the fuse blows up again... what does this mean ? did i short something, it's really strange ... the wiper works for 2 seconds again and dies ( when it blows up )

there must be something wrong with wiper connections?

Ok, maybe you can try this method. 1) you disconnect the connector from the wiper motor. 2) than you link a wire to the wiper motor for the battery, but be sure in between you have put a safety fuse. than you test it, again if your fuse blow, than your can confirm your wiper motor interner coil short, otherwise were be the wire or speed controll units short.

Question

May i know how your DOT light work. when you ON the wiper? or when you ON your Head light?

I have a bit confuse. assurme your DOT light are not work 2gether with yo wiper than i don't think your mechanic will link the wire to the wiper.

By the way what is DOT light?

dot light are day running lights, GTO's dont have em cause they are from japan and in my province you need them to register your car.
we fixed the problem, my mechanic just put in a relay for the dot lights and EMC if your reading you can add this to the problems of VR4 :
THE TRUNK IS NOT WATER PROFF !!!
we popped the moulding to check the rear wiper and it was fukkin full of moisture and 3 of the screws from the trunk lid were soaked.

NO car from 93 is going to have a perfectly dry trunk ;)

Ok, get a stick of chewing gum - the kind in the silver wrapper. Chew the gum, and wrap your blown fuse with the wrapper - silver side OUT. Force the wrapped fuse back in the slot and BAM (BOOM, FLASH, SPARK, etc.) you're done.

(just kidding - don't do that unless you like BBQ 3000GT)
