Hi, I'm not extremely engine savvy so i need a little help. I just picked up a Bosch AL77X for my 144. it bolts on great but the wiring isn't the same as the original alt. I sure don't want to hook it up wrong and ruin anything. Please Help.

Welcome to Swedespeed, Gabe.

Here is the wiring diagram for a 1973 Volvo 1800ES...

...which shows the alternater (#14) and associated wiring.

Also, here is a link to a short description...

...which may help.

If possible post some pictures of your old and new setup including any instructions that came with the new alternator.

Thanks.

Solid, Thanks! I've Got it in now and i'm pretty confident it's good to go. Here's how it looks: Fat red wire on fat post, two thin wires each on their own insulated post, fat black wire on 3rd grounded- post alone, green wire on tab. all the HUD lights come on right with the ig-switch on but I have to charge the battery back up before it'll start.

Correction- one of the single red wires is on a non insulated post.
