99 Harley Road King, no crank

Hey Crew, My 99 Road King just stopped running. It's a carburated model, I have a new battery and circuit breaker, It won't crank over via the switch, but if I jumper the starter motor, it cranks fine! what could I be missing? Thanks for any info. D.L.

Did ya check your fuses? Under the left side plastic side cover. Could be that simple. Believe it is a 50AMP

I found the fuse block with the five 15 amp fuses, and they are all good, checked with test light. I didn't see any large 50 amp type fuses. I traced power to a part mounted under the fuel tank at the front bottom of the frame that has four large black wires going into it. It is aluminum, and has cooling fins on it. The power goes into one side, but nothing comes out the other side. The connector was full of oil and water, and looked like possible heat build up. I don't know what the part is called, some kind of controller? It obviously gets warm to need heat finscat into it. Thanks for any help.

That is your Electronic Control Module (ECM) and they can fail as yours probably has.
I, too, have a '99 FLHR and mine failed this year. I replaced it with a single fire Crane unit. It wasn't a straight swap, as I had to manufature a mounting bracket for it, but I get FAR better performance with the Crane than the stock unit.

Do you have the service manual?

Large finned alum with 4 wires is your voltage reg. this would not cause your starter problem. Clean all the oil out of it and lets find the starter prob. Could be several things. 1. Starter sw at handle bar,2. Starrter relay. # soliniod on starter moter. If as you said that when you jumper the moter that bike will start i am asuming that you are jumpering to the "C" term on the motor. its the spade conn on the left side of starter has a single green wire to it. if thiis wworks then try the relay it is under rt side cover next to the ECM wires to it are Tan, should be a 12VDC constant, Green w red trace, 12VDC when relay is energized, Black with red trace 12VDC when starter button is pushed Last is black, this is the ground for relay must be less than 1 ohm res. If 12VDC is missing on the B/R wire then wiring ing bars is prob where the problem is. Have Bars been changed if their any taller than stock IE< apes then wires are suspect also did you just wash bike ? if water gets in to switchs this can cause problem till they dry out. Tech tip when washing never squirt hose directly at or into the switch housings this will cause multiple problems till they dry out. Good luck and keep me posted.

This has an ECM even though its carburated? I need to get a shop manual, I will go get one tomorrow. Thanks to everyone, D.L.

Ooops - too little sleep. I did replace the ECM & the coil at the same time
