The way you are saying it sounds like the alternator is going bad which will directly affect the ignition sys, being an old vehcle i would suspect the fuel pump shorting out

usually a recurring blown fuse has to do with excessive resistance on whatever that particular fuse controls.
I had that happen a few times on a car that I bought. the sway bar was bent into the radiatior fan just far enough to put pressure on the fan blades.

dont know this particular vehicle but locate your owners manual and the fuse box or boxes in your vehicle will be shown in it. there should also be a list of what each fuse in the box is so check them out and make sure they arent blown. if you dont have your owners manual the most common places for a fuse box are under the dash on either the passenger or drivers side, under the hood (usually next to the battery but not always), on the side of the dash (drivers side) as soon as you open the door and on rare occasions under the back seat or even in your trunk.

When turning on the stock stereo of the 91 toyota corolla nothing happens, lcd panel lights up but no sound or display, is there a reset code?

Radios often have 2 fuses, 1 for ALWAYS ON, 1 for ACC. It's possible that the always on fuse may be blown, if the radio isn't asking for a code. I'm unfamiliar with your particular car but radios can sometimes have a fuse behind them as well as the one in the fuse panel.

2002 dodge ram 1500 flashing red light and dead

When you disconnected the battery, you tripped the alarm which locked down everything. In your owners manual, look under the security or alarm system. It will tell you how to disarm your particular alarm system. If I am not mistaken on these you put the key in the drivers door and lock and unlock it 2-3 times. If you do not have the owners manual, you can contact dodge and they will walk you through it.

Engine fan keeps running

It's possible that the fan control relay is intermittently sticking causing the fans to run continuously. This can overheat and subsequently blow the fuse. Try replacing the relay and see if anything changes.

Hope this helps.
