what you proably got there is too high of resistance. So, go buy a cheap little multimeter and turn it to OHMS..the symbol for it will look like a C with the open part facing down and 2 lines coming off the sides..trace it back as far as you can go and you will proably find the problem..as heat goes ^ resistance goes ^ wich means less volts AC your getting..checking volts will just establish you have a problem and u already know you do so go right to finding where the problem is..if you need any help LMK im a tech (for ducati) but i know some people who know hondas like no other
