Repeat Lesson on Motorcycle Starting Issues

Last month I had learned that the starting issues on Yagi, my TW200, boiled down to a bad battery not providing enough power to start the motorcycle.  I had wasted too much time thinking it was a starter relay, or starter switch issue when I should have checked the battery first along with its connections. 

Today, June 6th, I relearned this lesson. 

I had cleaned out and sprayed graphite lube into the starter on my 2014 Ural Patrol, and it was still having sporadic issues starting the engine. 

This morning, I took apart the ignition switch, to clean it out and while doing so one of the wires going to the kill switch broke off.  Hmmmm, possible culprit I thought.

I managed to resolder the wire onto the kill switch assembly and tested it to make sure it worked before putting it all back together. 

Once assembled, I now had consistent starter issues in that it would not crank the engine on despite many efforts! 

Instead, I learned a new diagnostic procedure, at least when it comes to my motorcycles. 

I hooked up my old battery charger / starter to the battery on Scarlet and she cranked right up! Multiple attempts were made and all were successful. 

I disconnected the old battery charger and the problems returned, pretty conclusive I thought. So there's a new AGM battery on order via Amazon, should be here in a few days. 

The testing had basically drained the old battery enough that it would not provide enough juice to crank the the starter and thereby the engine!
