[silversr]

I have a 91 240 that im working on and when i put the alternator back on, and i accidently blow the the big fuse under the hood i jus wantd to know,do i have to use the same fuse becuz i used a smaller one but it just turns over it has fuel and spark and the timing is rite any help would be appreciated

I didn't think you could get any other fuse to fit!?!? I would put the correct one in, you are talking about the 75 amp fuse right? It will cause all kinds of problems with the fuse blown. It wont be chargeing, gages will be wacky then it will suck your batt dry and die. It might be the cause of it not starting. Check the other fuses, if that one poped, there is a good chance more did as well. Start there, make sure you have a good battery as well. Good luck

Nothing more I can add to this.

i jus put in the new fuse and a new battery and it still does the same thing it jus turns over im running out of ideas mayb the alternator itself?

[NIK90s13]

No, somthings missing,Is the battery good? Even if the alt. was bad it should start with a good batt, till the batt voltage in sucked out.

I take it that it was running befor you started the alt. change.

Does the starter sound any different than befor?

sorry for the questions, I'm just trying to think, you know how tough that is!!LOL

actually i jus got done rebuilding it replacing the bearings and rings then i go and drop it in today. the only thing that i dont have hooked up is the o2 sensor and the tranny sensors i dont know if that will effect anything

bingo!!! saaaame exact shit happened to me

1. 75a Fuse Kept Popping
2. A Fully Recharged battery kept dying over time
3. Car didnt run like it was suppose to

my alternator went bad, it was like $120 new one installed

[silversr]

ooo yea i put in the camshafts do i have set the clearances, i thought it would be self adjusting

[silversr]

but now the fuse doesn't blow any more

[NIK90s13]

What motor? I'm asuming it is a ka24de? the valves do not ajust, there are shims that you are supose to ''gap'' but it should run anyway, you are talking of thousands of an inch gap.
If you installed a cam, recheck your timing. that will cause it not to start.

[silversr]

so wat would be the easiest way to check the timing?i really dont want to spend too much time on it anymore this shit is stressing me out becuz i checked the timng before i put the motor back together lining up the marks on the chain and camshaft and crank

[Nizzan4u2nv]

This happened to me when i crossed the polarity. + to - and - to + Check your wiring. Its probably shorting somewhere or bad ground.

[silversr]

great news it was fixed the problem was the timing after all

[NIK90s13]

Good , was the distrubuter off?

[silversr]

yea the distributor wasn't aligned with the crank pretty stupid mistake, well u learn from ur mistakes

[NIK90s13]

It's cool, Glad you got it!!
