750 ignition wiring upgrade (attn. jcslocum)

Hey Jonathan -

I'm going through the PDF to do the wiring upgrade for improved starting (the addition of 2 new 30a/12v relays) and I just realized an inconsistency:

In Step 5 , you clip then pull the 12ga brown wire from the main power feed plug under the tank, attach a female push-on connector and indicate it will be connected to terminal #30 on the relay.

Later, in step 7, you add the 30a inline fuse to the battery feed post on the starter solenoid with a ring terminal, and attach a female push-on connector to the other end - and that will mount to post #87 on the relay.

However - and here's the conundrum - in the diagram under step 9, you show the "Power feed from starter solenoid. 30 and fuse" going to the vertical post #30, and the "Brown wire cut from the harness that goes to the fuse panel" connected to horizontal post #87. Those are backwards from the written instruction.

So ... Which is the right one?
Thanks in advance!

Jake

Jake,

it doesn't matter. It'll work both ways. Contact 30 and 87 of a relay are not directional.
If you want to stick on what's printed on the relay 30 is the number for battery +.

Oh, good to know. Makes sense. I wound up running the battery+ from the starter solenoid to post #30 anyway. But what you said makes perfect sense - a switch is a switch. Thanks, G.

Hope you're doing well - it's been a while!
