Re: HOW2 measure alternator output on '90 Turbo 200 ?
Your alternator is the 110 Amp version.
You could check voltage output with a volt meter on the main connection on the
back of the alternator when it is idling (dangerous). Then check voltage and the
jumper terminal just in front of the air intake box / air filter. Next check the
voltage on the battery under the rear seat. It should be nearly the same as the
alternator or jumper terminal. If it isn't you have a bad / corroded splice
under the carpet by the passenger kick panel.
If the battery light is not on on the dash when it is running you probably do
not have a problem. If the light is on you could replace the brushes and voltage
regulator in the back of the alternator. Easy and cheap - just two small bolts.
What causes you to think you have a problem?

Thanks Tony.
I tightened the alternator belt but the dash meter shows just over 12v
which I assume is the voltage output to the battery. I charged up the
battery before tightening up the alt belt. I guess I'll have to wait and
see if the battery goes dead again since I'd like to NOT crawl under now
that it's about 95 deg. here, now

If it only reads 12V when it is running then the alternator or its voltage
regulator are almost surely bad. You are running the risk of being stranded.
