Electrical Question
It is for the starter circuit between the relay (50) and solenoid (51) on a 77 FXE.
I see #2 copper or apx 1/4 for 180 amp. Sounds way to big.That's got to be wrong.

Am I wrong?
Got my son to pull my manual. He says that's the solenoid. 51 is the start button/starter relay/key. Doesn't see an amperage for it, however. Just guessing but 30 is probably good as long as it's smaller than the harness wiring. I would probably just soldier in a small in-line plastic case for a replaceable BUSS fuse.

I discovered the 14 gauge wire I used in place of the fusible link between the relay and solenoid came apart and shorted against the frame.
The stock wiring for this set up is a direct + from the battery to the relay, solenoid, and start switch (the small red wire in the photo).
This is actually a pretty serious circuit since it carries 12 v direct from battery all the time.
According to the link on fusible wire posted above, the fusible link should be 4 sizes smaller than the wire used. Since I'm using 16 gauge wire, the fusible link should be 20 gauge. 20 is rated at 11 amps. So, I'm going to go that route and put in a 10 amp fuse.
Keep my fingers crossed.
