When starting the motor is it normal that it slowly turns over even when the battery is hooked up to another car? I thought it usually cranks over really fast.
check your battery and ground connections. remember, even if you have a reactor hooked to the battery, if the current cant get into the battery and out to where it needs to go (connections), it will crank slow.
you can use jumper wires to enhance the existing cables for testing purposes.
my car did that.. turned over pretty slow with a fresh charged battery. go out and buy a new positive battery cable, and get it in a bigger size, like 0 guage, or something larger then the stock.. helped out ALOT. my engine turns over and starts alot faster due to more current flow
Just food for thought...I had the same problem. I went out and dropped a wad on a optima battery, and it still cranked slowly. Also changed pos and neg cable. No help. Finally, figured out it was the starter. The thing cranks fast now, at a high pitched whine.
