Thanks guys for the guidance. The battery I put on the bike is a budget battery from amazon.
https://www.amazon.com/dp/B0131FZKW8?psc=1&ref=ppx_yo2ov_dt_b_product_details The battery got good reviews but I'm thinking you guys may be right, this battery my not be powerful enough to run the computer. I charged the battery and the charge reads full charge. The engine trys to start and will start for a few seconds but when the throttle is applied the bike dies. I have noticed that the bright light for the headlight will not come on either. When I attach the battery jump starter the bright light will come on but as soon as the external power is removed the bright light goes off. i am totally confused and not an electrician, but I know that the bike isn't getting fuel.
Does anyone believe this battery could be the culprit? Are the any recommendations for a good "budget" battery at least until the problem can be isolated? The bike came with a YUSA BT12B and I replaced it with a Shorai lithium battery but they are both dead. I don't want to spend a lot on another battery until know for sure that is the problem.
Also, a few years ago I had to replace the electrical rectifier that is under the seat. It was having symptoms of a failing battery, and I thought that was my problem until I was trying to start the bike and smoke started coming from the rectifier.
The not starting issue I'm having seems similar to the bad rectifier but without the smoke.
Please help!
