Besides the regulator/reluctor sticking in the alternator, is there anything else that will drain my battery down in my 81 Vette?

I know the radio has a memory and the car's computer (may) draw something but, if I'm NOT seeing any lights on etc when the car is off what could be killing the battery in a few days of sitting?

Note...7/09 I did replace the alternator because it WAS draining the battery. I diagnosed this by killing power to radio, internal lights etc...then...removing the + battery terminal and noticing a small spark when reattaching it. I then did the same test with the +alt wire removed > no spark at the +battery.

Now, once again the 4 month old re-manufactured alt is doing the same thing??? ]]> C3 Technical and Performance HammerDown http://www.corvetteactioncenter.com/forums/c3-technical-performance/118549-battery-drain-down-problem.html Question: Wheel Alignment?????? http://www.corvetteactioncenter.com/forums/c3-technical-performance/118538-wheel-alignment.html Thu, 19 Nov 2009 14:21:21 GMT Good morning C3 Panel of experts.....................

I have a 1970 LT-1 and the Temp Gauge does not move it is stuck at under 120. I wanted to check and see if the sending unit was the problem and the only thing I found was bolted into the passenger side of the block and it looked like the Temp Sender In Head not the typical temp sending unit.

Can't remove the four bolts connecting the half-shaft to the trailing arm!]]> http://www.corvetteactioncenter.com/forums/c3-technical-performance/118475-cant-remove-four-bolts-connecting-half-shaft-trailing-arm.html Mon, 16 Nov 2009 15:15:32 GMT I'm started my trailing arm rebuild project, and I've got everything disconnected except for the half-shaft and the forward pivot pin. I' went to take the half-shaft off the spindle. . .and I found that three of the four bolts are seized in place. My impact wrech isn't making a dent. . .and a breaker bar is not working either.

I soaked the three areas un PB Blaster last night. . .and I'm going to try to hit it with the impact wrench this evening. . .but I've never really had any success with any penetrating fluid. So. . .assuming this wont work. . .any other suggestions?

The only torch that I have is one of those gneric blue bottel torches that I use for plumming. If I heat the area up with that. . .do you think it will help? Or is that not hot enough? If I do heat it up. . .with that alter the metal's strengh. . .therefor preventing me from re-using parts?

I'm just a home DIY-er so please provide ideas that are do-able at the house.

I managed to change the front left caliper with no problems at all, but I've run into a big problem with the front right:the brake line fitting is rounded off. How do I loosen the fitting without making it any worse? Does this mean I have to replace the whole brake line (which seems like a royal pita to do without removing the body from the frame)?

I really need you help on this one.

Last year I've got my car on the dyno and got 225 Hp at the wheels. This year I've installed brand new Patriots cylinder head part # 2181 64 cc aluminium.

Then Put the car on the dyno, what do I get? 225 HP at the wheels. What the f***k just happened? I had the smallest cylinder heads a L-48 engine could come with. There is no way I shouldn't gain a good 40 HP at the wheels.

I know at the dyno, we could see blue smoke coming out of the exaust at High RPM's. We got a full dyno tune up on my car and could only come up with 235 HP at the wheels. the guy at the dyno told me that the engine was probably warn because this engine should be pusshing 300 Hp at the wheels.

Here's my setup

350 L-48 chevy engine
Comp cam 268 Xtreme Energy Hydrolic flat tappet
Edelbrock performer EPS intake
Holley 770 cfm street avenger carburetor
Patriot performance cylinder 64 compression chamber part # 2181
running on headers and chambered exaust. true dual exaust

Now one thing I should mention, since I've put these heads on. I'm getting backfires coming throught the carburetor.

Is this a distibutor problem? I had the car timed correctly, changed vaccum advanced canister, timing cap, wires etc... I have an electronic pertronic conversion in the distributor as well. The car works really good when I drive besides those backfires once in a while through the carburetor. But the power is just not there. I should have more condisering the parts combination on this engine.

And by the way, I've checked compression in my cylinders and I have 150 psi in each cylinder. Should i have more? Is my engine really warned out?

Please help
