I'm with Mudgeon, it could easily be a single bad battery. You need both batteries in good shape to get enough current to start

Test BOTH batteries with multi-meter while someone turns the key to try to start it. You should see 12v or more at both batteries. If one battery has a dead cell, jumping from a 12volt vehicle may not be enough current to lock in the 24 volt...

The converter relay is expensive, and maybe hard to find as well. The main reason I did the 12v conversion was to achieve a true dual battery function. I can have one battery go completely dead and I can still start the cruiser. At the same time...

HDJ's with a "cold weather" package have a 24 starter. The rest of the system is still 12v, but there is a relay that energizes and puts the batteries in series to make 24v for the starter.

There is a relay that switches the batteries from parallel to series, I think it's called the 24v converter? It's a super common failure point on the 24v start system. Lots of folks, myself included have done a conversion to a 12v starter.

Do you still have the 24v start system?

Thanks for the reply, however I still don't understand. The FSM has a whole procedure for selecting the correct size bearings, and there are 5 different "MK" sizes. But these Taiho bearings somehow all magically work? Do the OE bearings have...

I am in the process of having my crank repaired, I had a harmonic balancer fail and damage the snout. I am planning on replacing the BEB's while I am in here, but I have been running into trouble figuring out which size bearing to order. I...
