CS isolation question

hooked up my new charging system in my 99 fbody and came up with a problem . Here are the basics of the charging system .. I have a stinger 1700 batery in the back and a excide gell cell up front , the alternator is a hi ouput powermaster and was installing a powermaster 904 200 amp 3 post isolator..

The problem ive learned is that the LS1 style alternators , and in my case the replaement hi powers one is a "CS" style , i learned this the hard way tracing down a lack of charge problem.. As i understand it our alts "fbody" will not kick out any voltage unless it sees a charge from battery .

Ie on a standard isolator when alt connect to alt post and battery to battery 1 post no charge comes out of alternator ,, but when you connect the alt to batery cable or touch to battery terminal one , the alt fires up and kicks out great voltage.

I would like to use the 200 amp isolator i now have and am looking for a way to use it , I could jumper alt post to bterm 1 i guess but i dont know if this is a good idea or if i shoulld return the isolator and get one that handles a cs alternator , which seems to me to be same thing just has a "excite " wire or harness , anyone have any ideas or suggestions on how to use current isolator or what to do i would appreciate it

LOL - mine was a higher end model too - iirc deh-9300. Low mileage too, it was sitting around for year collecting dust.

One or two, they are still subwoofer outs and are mono summed signals from both left and right. Even the 2 RCA subwoofer pre-outs on the 2nd one...
