My HD 2001 Softtail will not start due to a power drain when i turn it on.

SOURCE: blows ignition fuse when key is turned on

Look for a grounded wire on the ignition switch or a break in the wiring leading to the fuse. Wiring system on motorcycles are a close system with only the battery being grounded to the frame. Any loose connections or breaks in the wires that will allow the current to jump to the frame with cause you tons of fun.

Check the battery, try jump starting it with another battery. If the battery voltage drops too low, i believe the alarm default is to disble the bike. (Greasy little criminals will cut battery cables to disarm the alarm) so although you may have enough power to operate the lights and alarm, it may be droppoing too low to start.

I have had the same problem. Been throught two batteries, new cables,checked the fuses 999 times. It only starts every now and then. You must take a wrench and get the positve cable just right and it will start for a week or so then back to the same thing. You would think after building motors for so long Harley could at least make a bike that starts.

SOURCE: No power when the key switch is in the run position

Isolate the igition switcw again and set your meter to ohms turn key to acc. test red and red/grey wires 0-10 ohms then turn key switch to on test red-red/grey then red-red/back, then red/grey-red/black again 0-10 ohms the higher the resistance the lower the voltage. Now if that tests ok then it is plug and play i would go to the ground side and check the resistance there is a common ground on the left side of the bike check that for loose or broken connection good luck

Testimonial: "appreciate the advice, it was very helpful. Thanks!"
