No start, ?Batts?

Finally got the "new" key switch into the blazer. Now I have the wait light, a GEN 2 light and a clicking noise when I try to turn it over. The batteries were taken out, put on a charger and read as fully charged. They also showed over 13 volts each. Is it possible their still bad. They show a 2005 manufacture date.
Both of the hot terminals have cracks in them, but they clamped up tight.

Put a load tester on the bat's. If you had just charged them they will read 13v or better, but are they holding the charge? Its tough to get a cucv started with questional bat's.

Forgot to mention, the volt gauge in the cucv read very low also. I don't have a load tester. Dosn't it take a carbon pile load tester to really test out a battery?

I just always use the load tester that I have at the house, maybe a 40 dollar one. Take your bat's to just about any parts store and they can test them for free.

Just in case the batteries are good, what else would it be?

If the bat's check out good, next thing to do is download the TM's from above in the FAQ's, Use the trouble shooting from the TM. That way your arn't throwing money at it blindly. Could be any number of things, ie starter, relay, fuseable link......But you need a mulitmeter so that you can check voltage.

Start by checking all your connections on the large battery cables. If your batts are checking ok, but your voltmeter in the dash is reading way low, you have a poor connection.

It would make sense. It started with a jump. Might just be those battery connections or the batteries. If not, I'll do the TM thing. Many thanks all. I like electrical work, but these cucv's have a few extra's kinks compared to the usual GM.
