Question about Ford Focus
No power only radio and alarm i think there is a wire missing from the positive battery terminal i have 2 thick wires is there also a thin red wire
If you have security on the vehicle it might have you locked out. If so unhook the battery and start over, hook the ground up first and the positive up last ( sometimes we have to do this to reset the security)
if this still has no effect the look at the ground wire, if the radio works then the battery is making a connection through the small ground wires so check the large wire for starting.

Use a 12 volt DC test light, or a DC voltmeter & probe until you find one wire/terminal that has power constantly, whether key is on or off. That's the one to join it to, for your memory. Your radio power wire will go to the other unless you want to be able to have your radio working all the time when you turn it on, regardless of whether key is on,or accessory position, and if that's your preference, join it to same.

there are a few small wires on the alternator and one is a feedback for the alternator to switch on and charge the battery.there is a fusable link which looks like a piece of wire,but it is a fuse and if your alternator was blown,or a jump start was done wrong,it could take out the fuselink and your alternator is not putting out voltage.get a diagram and check to make sure that all the voltages for feedback are ok

I had the same problem with a Tercel, it was the distributor cap had a non-visible hairline crack in it and allowed moisture in.... does it do this only when it rains or high humidity?

Replace the Alternator. Sounds like the internal brushes have worn out as you appear to have the correct feeds to it. If you are tempted to open the alt to have a look at the brushes, be careful as incorrect assembly can cause serious damage as can incorrect re-assembly. You can simply replace the brushes but I would advise against it as the copper rings the brushes rub on (the slip rings) will also be worn and require replacement, this is difficult if you do not have the experience. Also, the bearings should also be replaced as they will no doubt be worn too. Altogether a specialist job, so grab yourself an new or exchange alternator. if you have to get a second hand unit, have it tested BEFORE you fit it..
