I've gotten confused about the m1009 alt set up and have a few questions: 1) Are both alt's floating ground? Or is the passenger side the only one? 2) Can any GM alt replace either alt? 3) When converting to 12v, can you use either alt (floating ground or not)? 4) When converting what dose "removing the ground from the system" mean? (quoted from the official 12 volt convert. instructions that someone will direct me to, I've read it 20 times). 5) I assume from reading said instructions that all you need to do is ground the single alt to the block and now its not floating, right? Please help Thanks.
