1985
Mazda
RX-7
(engine size unknown, it is a Rotary Engine)
60,000 miles
Ok here we go. We have had this car from 1985 till now, usually kept it safe in the garage and would start it every so often to keep it running. With a need for three cars we decided to get it up and useable again. We took it to the local Mazda dealer and had him do a good once over and he said everything is fine. We have been driving it with no problems for about 2 weeks now. No funky noises or anything. This morning I went to start it and it started fine. (It takes a while to really start and we have to rev the engine for about 30 sec or so, but no real problems.) This morning it started fine. I put the clutch down, shifted into first and released the hand brake with my foot still on the break. I took my foot off the break and stated on the accelerator to begin to shift it into gear. The car jolted a little as if I was releasing the clutch a little too fast, and turned off compleatly. Now when we turn the key no lights or anything turn on, and not even clicky noices are heard, nothing. What do you guys think is the issue. I will check back often and answer any questions. Thanks.

Check the battery connections. Although the make look 'fine' on the outside, you could have a poor connection between the battery posts and the terminals. Also, check any leads that come off of the terminals. Corrosion is a common problem.

I will try that thanks. I just took the battery out of the car to test it with a battery tester we have, and it says its full. Like you said The connections might be coroded, they look a little gunky. Should I use sand paper? Or what should I use?

You can steal some of your wife's baking soda, dampen the cables and terminals, then sprinkle the baking soda onto them. Be careful not to get any into the cells of the battery, though. May take several applications. You can buy a battery terminal cleaner at any parts store...Very inexpensive, and nice to have around. Emery cloth on the battery posts works very well. A knife blade on the inside of the battery terminals works, just be careful not to take too much 'meat' off of the terminals....lightly scraping, only.

I guess we had had this problem before and this was in fact the fix. We now keep a wrench in the car to tighten the nuts and scrape if need be. Thanks for the help. Everything works great.
