Safety trim wiring in parallel

I don’t know why my pictures are posting so small. Hope you can still see

Your servo is likely rated for way less than 5 amps, hence 22 ga wire. If so this is the wiring diagram currently being used:

Hold on - check with TCW 1st - sounds like the HD may stand for heavy duty which would be for a much more robust servo.

I'd ask if you can pin per the current diagram or "un-pin" the duplicates from your current harness. Assuming you have a servo of less than 5 amps draw (most are less than 1 amp for this application).

According to this thread Eddie talked to John M and John said it was 7A.

So what’s the best way to wire the two parallel to the trim motor? Shorten up the 22awg wires coming off the motor as short as possible?

[Danzer1]

I don't think that is correct. 7 amps at 12 volts would require a much larger wire size than 22 ga. for any distance. Maybe .7 amps? What is the brand and model # of the servo?

Not sure what the AWG is on mine but its bigger than 22. More like 18 or 16.

I went into the garage and put a micrometer on the bare wire. Looks like .0415”. So I guess that would be 18AWG. My mistake. The wire seems smaller but I guess that’s due to a thinner casing

Thats part of why I'm confused. The kitfox diagram shows a 7.5 amp fuse - so a 7 amp draw would then make sense for a load. I know they use a more powerful motor for the tail trim than the Ray Allens. That would equal about a 1/10th HP at 12 v. Which would require a much larger wire for any significant length. So why would they put a 22 ga lead on it, which would then be the weak point when it's got to be wired 10 feet or even more that would dictate 14 ga. or maybe even 12 ga.

So Josh's question of why a 22 ga lead is valid and makes no sense to me either unless the amp draw is actually much less than the 7 amp answer given so far.

edit - forgot to add: And if the amp draw is less, I certainly wouldn't want to be protecting the circuit with a 7.5 amp fuse or breaker - it will never protect anything - especially a 22 ga wire sizzling! Further - if it really is a 7 amp draw - would you want to take a chance on a 22 ga lead sizzling?

Somethings not right here, still
