1. My car has been sitting for awhile, but it has started up when I needed it to.
I recently took out and put back the transmission. I got everything hooked up and the car would not start. I took a reading across the battery terminals and got 11.87 volts. Is this an indication of a dead battery? 2. I should mention that I unhooked the positive and negative terminals while the trans was out. I also have a battery disconnect on the negative terminal (turn a screw to connect/disconnect). I got sparks when I hooked up the positive and touched the wrench to the car accidentally. 3. I have an Optima Red Top battery that is only about 1-2 years old. 4. I checked all the wire connections related to the trans and didn't see anything. That shouldn't matter anyway, I think. 5. I'm thinking of jump-starting the car and seeing if that works. 6. I'm also thinking of getting a battery charger and hooking that up. Thoughts? |

Just did all the above. Ended up buying a new red top ($200.00 ish) They said I need the smart charger for the OPTIMA's. I was using my standard charger (trickle) and It wasn't holding a charge, although I could use the boost on the charger to get the car running. The car idled fine in the shop, but the test drive was pulsing or surging. like on/off the ignition. the car would also die at stop/lights. I've been having carburator issues...now 65 idle jets (from 60) and I'll try the 200 ac that I have (now 180 ac). webber 44 idf
It was also suggested to buy the yellow top (deep cycle) and it will take a charge easier on a car that sits in the shop for short times. |
