I'm having problems using a 4" Novak sensor harness together with a Tekin RS and Redline combo. The motor cogs to the point it will not rotate and the ESC overheats. I've tried two new Novak harnesses and same problems. I've tried two different LRP harnesses and no problems.

just get a tekin one or use the lrp. Novak and tekin components dont like each other im finding out the more research you do

But it seems so simple since the harness is just straight through wiring. How can anything go wrong? Can length make a difference?

Not sure but i know novak motors dont like the turbo feature of the tekin's at all
