How can i find the fusible link on a 1997 buick lesabre

buy a $15 voltmeter and end throwing parts an going broke.

while jump started it runs, (you forgot that key fa
and running after the ALT swap the charge battery lamp glows.
and that means ALT changedwith battery neg lug not pulled
that means the 100amp ALT fuse was blown out doing that wrong.
jumper start it again see that lamp glow?
then battery voltage is 11 to 15vdc, below means fuse is blown./
mean ALT is dead or 3 fuse too it blown.
the huge fuse can be a Fusible link type, ignored by noobs
9 of 10 says good and forgot the Huge ones./ or fusible link.


see the black code (buick code) fusible link hear
voltage must be same both sides of it, engine running
or it is blown,
step 1, new alternator put in ,is NEG lug off first or BOOM./
black code. 105 amp ALT, so fuse must be more. (a tad)
raw links are 9" long max
the diodes in ALT seen blow 3 phase can short and you never want a harness fire in any car, (near fuel) ever.
so it must be fused. as it was.
what I do is upgrade to real fuses and small ;block to hold it.
120amp fuse. called maxi fuse.
I'd go FL12 links here the insulation is very special on them

If you are running an big 130 or 140 amp alternator, 6 guage would make sense for the charge wire #1 with a 10 guage fusible link to protect it.
yes hard to find them,, so upgrade to maxifuse is best.

No power to whole system ??? Nothing ? Turn the key to run an instrument cluster doesn't turn on ,no warning light's . Factory service info shows no big red fuse on the battery cable .Battery cables connect to fuse box ,under hood and under the rear seat . Wiring behide pass. right rear tire is fuel pump , rear lighting . Nothing that would blow a main fuse . This vehicle has no fusible links .

Not sure you mean the lighter or the fuse for the lighter.
The lighter should be close to the ashtray.

The fuse should be behind the ashtray under the dash. It may be a fuse or a fusible link.

Hope this helps.

posible a bad fusible link or ignition switch

Yes --if you want to do serious damage even have a fire. The fuse is there to protect equipment and wiring. Better to fix the short that is blowing the fuse

You more than likely burned out a fusible link. It's an in-line wire that acts as a fuse that's usually attached to a large red wire.

I would check the connections at the battery for the pos. and neg. posts or side posts. If it cranked, then it should keep on cranking for more than 5 sec if the connections are good and the battery is fully charged.

There are fusible links, but they generally won't blow because of cranking.

Good luck on this repair.

sounds like a fuse blown under hood in black box on drivers side. don't know it your search included that
