Car has been on the road for a few weeks now and the battery I had when I bought the car just died. It was 5 years old i figured it was time.
Went out and bought one that has 1000 cranking amps. I was not messing around. It spun the starter so fast that I didnt even hear it, I turned the key and the engine was on. It was pretty cool.
Well today I noticed that the engine was cranking slow, so slow that I took it home and began troubleshooting. Battery is 11.90 volts. Turn the car on and take a reading, 10.50 volts. Disconnect battery as car is running and measure from wires , 7.50 volts. I wanted to try it again but the second time I pulled the wire off the battery the car just died.
So I went to Autozone and found out I had bought a battery that only puts out 40 AMPS. I am pretty sure that my electric fans draw 30 amps, this would explain the dip in RPM everytime the fans came on. How much draw does a MSD Digital 6 box pull? Plus gauges...brakes lights, radio. I am suprised the alternator lasted for 2 years.
I could imagine trying my nitrous out and only having enough juice for one solinoid, I bet the fuel solinoid would not have come on.
