Default May have done a dumb thing help please!

I have a 76' l82
I have been wanting to check the timing for a while, first I had to get a timing light witch I did last Sunday. First thing I had to do was install a timing tab on the timing cover, because there was none on the cover. Now to the problem, when I hooked the red clamp on the alternator post where the red wire was and the black on the alter. bracket. The timing light showed the rpm I was about to check the timing mark on the balancer when the light started to smoke, I unhooked it real quick. What did I do wrong. The timing light is a craftsman with rpm/adv. I did get a extended warranty unless they said I hooked it up wrong. But I can't see how.
Help please
Larry

Probably made in China. Return it and get your money back.

Return the light for another one. At least it wasn't your alternator smoking so it's just a faulty light.

What they said.
Craftsman isn't what it use to be.

Since you don't know the difference between which and witch you probably won't understand any directions you get here.

You did not do anything wrong in how you connected your red and black leads. Especially if you were certain that the red clamp stayed on the terminal stud of the alternator and did not ground out. When that occurs...it will usually sparks like crazy.

And for what it is worth:

Putting on a timing tab and hopefully it is the correct one where the gauge portion is very close to the circumference of the harmonic balancer....as it should be. AND....

Unless you KNOW for a FACT that the harmonic balacner is NEW or GOOD. Using a timing light trying to get to the 'numbers' that many people get all caught up in MAY be a waste of time.

Reason being....IF you do not knwo for a fact that the balancer is good....you could be setting your timing to the NOTCH in the outer ring of the harmonic balancer that has MOVED.....thus....not correct.....and thus.....your timing results in 'numbers' is all messed up. I KNWO this for a fact because unless I knwo the balancer is good....for a fact...I have to verify that the notch for timing in the outer ring of the balancer is correctly positioned so my timing results can be relied upon as correctly accurate.

Just so when you hook it up and come back saying the timing was 'x'...and were concerned because you can not get it to where it 'should' be....I would not have to tell you about this issue...which can occur...because I have dealt with some balancers that the outer ring have spun 3 inches from where they should be.

Thanks Dub I just know the car runs on after I drive it and turn the car off. I have read that it could be timing. I do not know if the balancer is good or not. As for the tab I put it on to see if the timing is close or not. It is a large balancer with just about 1/4 of an inch clearance. I know to get number one up on the compression stroke and then see if the timing mark on the balancer is close to the timing tab.
Thanks again
O by the way I could not find out if that one step primer I bought would work on butyl tape so I saw where one posted he used crlaurence had primer made for butyl tape, so I have a can coming.
Thanks for your help on both problems

The car runs after ignition switch is turned off? Am I reading that right?

If so does it knock/rattle/sputter when this happens?

Turn your idle down a little, and it should stop doing this.

Doesn't matter , power from the battery or alternator + post . All the same thing. Take the defective timing gun back. I have an old Craftsman gun about 25 years old and still going strong but they don't make things the same today.

Balancers are known to spin on their centers throwing the timing marks off and it is sometimes hard to determine this. I always thought they should put matching alignment marks on both pieces when they are put together so it is obvious if it moves at all. Maybe someone is already doing this , I am just not aware of any.

Larry you can hook to any battery source if you have another battery just sit it on the ground an hook it up you might have let the red touch to ground it doesn't take much lotta amps at that connection

DUB, BJ

Is there any way to verify or fix the timing tab position?
