Ummm rookie question... The output is the big red wire right. Wow did I really have to ask that. Apparently!

I run the chrome 2 wire 130 amp can't go wrong... gauge should read 13v or a bit higher while on

Hey Glencoe any chance you can send me a link? Thanks!

my bad bro Idk what I was thinking I'm running the 1 wire but here's a pic anyways

Did you get this from the big box stores or did you have to order it?

I got it from my local performance shop

I'm kinda going through the same thing only I have a yellow to purple, I don't know where it's  supposed to connect I thought I knew where it was supposed to go but when I turn the ignition key off the boat kept running so that's obviously not where it's supposed to be to charge my battery is anybody know where I'm supposed to hook the purple wire up   "see pictures"

Got the new alternator from DB electrical. Super cheap and got here quick! Couple questions,

1) the new alternator has a smaller diameter mounting hole on top and won't fit on the rod coming out of the block, just barely. Can I drill this out or is there like a reducer fitting to change rod?

2) lame question but does this fan look like its a cw rotation?

3) am I over complicating the install? The old alternator has two wires. I take it only the power is used?

Thanks SCJB

I had a one wire alternator for a bit. Kept drawing off battery and eventually it got burned up. Don't they have built in diodes?

These 1 wire alternators can drain a battery while sitting.
Just unhook or shut the batteries off when its sitting in the driveway.

Looks good
