I did just type a big response, but just hit the wrong button, so here's just the summary!
owch! i hate that

I am having second thoughts about my tactics (ish)
its an 08 CDI and I measured through the lighter socket with a cheap meter... ill take my fluke out tomorrow and see what It reads at some heavier terminals

I have been convinced that I should be pushing 14.8v into my auxiliaries for at least an hour after they stop drawing lots of current... if I can get anywhere near that out of my alternator ill go with a split and maybe boost the voltage a tad somehow....id have to manually isolate it though... and watch an amp meter for it to tail off... why is shit never easy ? LOL
