Re: no electrical power
Are you sure you checked all of the fusible links, that is the most likely cause of your problem. They will usually look burnt when they go out but not always, sometimes the burnt place will be on the bottom side of the wire and not easily seen. Do a continuity check on all of them but be sure to disconnect the negative battery cable before you do.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Usually theres a plastic valve mounted on the booster thats connected to a vacuum source. Remove it from booster(they usually just pull out) & hose, then suck& blow on one end. Air should pass only one way. If it passes both ways the valve should be replaced. Check to c if hose holds vacuum by placing thumb on hose end to feel for suction (motor running) & to listen for hissing. Replace hose if suction is low &or hisses. Could be a vacuum leak elsewhere in wich case performance would suffer & idle would be eradical.
I assume that you have disc brakes. These require a piston/s to push against the pads to tighten them onto the discs. 2 reasons they may not be working are the calliper pistons are seized up in the callipers and 2 the brake booster is not providing the power assist to actuate the callipers. If you have vacuum booster I would repair/replace the booster or check for vacuum at the booster hose. If you have electric pump booster then check that the pump is getting power and is working.
Main cause could be something stuck in the lighter socket. Sometimes, the ends of the car charger for a cell phone of GPS will separate, leaving the end in the socket itself. Placing the cigarette lighter back int he socket while there's something already in the socket will cause you to blow a fuse.
whatever you do don't put a bigger fuse in because it'll just cause more problems. it's either that there's a damaged or burnt wire or something inside the stereo has gone. so just check the wires and if they're alright it'd be easier and cheaper to just replace the stereo instead of trying to find someone who'll fix it.
Remove the large vacum line to the power brake booster .start engine and put thumb over the end to check for vacum. should be alot. Also remove plastic check valve and blow on it both ways. should be able to only blow one dirrection.If no vacum on brake line then it is not connected to engine vacum. if all checks good ,bad news ...brake power booster bad ,and only comes with new master cylinder...about 200 bucks and very tough to install..Brake master cylinder probably leaked fluid out the back and broke diaphram inside booster..hope that helps...let me know
Some of it went into the slaves as the shoe material was worn away.
Brakes are pretty important to have and to have work correctly. If you are not absolutely certain what you are doing and how it is to be done properly, please don't do it. Have this repair done by a professional.
The brake booster/ naster cylinder is located on the firewall on the drivers side of the vehicle. The master cylinder has a resivour (sp) which has a cap and holds brake fluid. The brake booster is right behind that, the master cylinder is bolted right to the booster. The booster looks like a big circle about 10 to 12 inches round and usually 4 to 6 inches thick. It will have a vaccum hose coming off the booster and going to the intake manifold. The master cylinder with have hard lines coming off it which are brake lines. Hope this helps.
