UPDATE: This is what I've checked so far. Fusible link is good and there is power going to the alternator and distributor. When the key is turned off there is 8-9 volts going to the back of the relay block (thick red wire and thick white wire). When I turn the key on it drops to .3 I looked all over for an alarm but found nothing. Also removed all the extra wires that were there for the stereo and something else (amp I think). Could it be something in the ignition switch? I still have no power beyond the relay block. I also took all the relays out and checked with key on and off and got the same result. I'm stumped.... Does anyone have a detailed schematic in digits that they could send me?


I just got this along with an FJ62 and FJ55 so I'm in the learning phase.
So I was checking compression on my parts FJ60 today. Since it has no fenders the battery is sitting on the fenderwell. I warmed it up then was taking out the spark plugs when the ratchet hit square on the positive of the battery (Glad I wear gloves!). Nothing better to ground than a spark plug huh.:doh: Now I've got nothing, no power anywhere. I just got this and haven't gotten my Haynes manual to look at wiring diagrams. I looked through a bunch of previous posts about fusible links which I know nothing about. Is there a primary fusible link that would cause this and if so, where abouts is it?
First I tried to jump it, then swapped out for another battery but it had no effect either way. Connections were tight and there's no corrosion so I'm pretty damn sure I fried something, question is what?

Very near the battery (positive terminal) you find white and green connectors with three short wires between them. You can disconnect the assembly, the connectors and wires are only about 4 inches long. I forget the colors of the wires but there are two smaller gauge wires that are the same, and a third goes to the alternator (White) and into the harness.

HTH,
 
Yes it should be just a few inches from the + terminal.....its a plastic piece
 
You should test it with an Ohm meter or test light. You're looking for continuity. If you simply by-pass it you risk creating a "new fusible link" somewhere else in your wiring harness. But it seems we know what caused it to blow and I'm sure you'll refrain from laying tools on the battery in the future.

You could include a fuse in your bypass wire but the tough question is what rating to use. My understanding of fusible links is they blown slowly, in other words they can withstand short peaks of current. Regular fuses blow fast so they may blow where a fusible link wouldn't. I think the larger Maxi fuses blow slower and can replace fusible links.

I hope someone knowledgeable corrects me if I'm wrong. ;)

All that said, if I was you, I would probably try bypassing it as you described. Just don't say I said so. :)

:idea: Re-reading post (about switching the battery) makes me think you really need to make yourself a test light or pick up a cheap one. A simple light bulb with a couple leads with alligator clips is very handy. Also, you can get a cheapo multi meter for about $5 to measure resistance, volts, etc. Just a thought.
 
fusible link sections are short, usually right off of the battery, and they will feel kind of soft like a wire that's not good.
 
Thanks for the advice. I just bought a new test light so I guess it's time to take it out of the package huh? I think I figured out what the link is, green plug on one end, white plug on the other. I'll try that and see what happens.
Thanks
