page 2 right below #9 is the wiring diagrahm

now my issue

i just finished wiring up the isolator.

i cut the wire from the alternator to the battery and ran it to the isolator at the correct terminal (A).

i then ran the wire (all 4 gauge) from the correct terminal to the main starting battery (1).
wire was also run to the second (stereo) battery (2).

i then hooked the "e" terminal up to the ACC fuse slot inside the drivers side door for switched power. the battery was disconnected while wiring was done.

now when i go to start the car it will crank and crank and crank. it started the first time but even mapulating the gas pedal i couldnt keep the car running.

also while the car was momentarily running the volt meter in the dash was only showing 11-12 volts.
i am recharging the battery now.

please give me ideas on what to check

thanks

 

Not sure you needed to go that far. You should have been able to get away with the Group 1 wiring (Assuming a V8 93-97 Fbody, as I'm not 100% on the other years).
