YouTube is your friend. Learning how to check voltages and current consumption will help with battery related projects. Also look up videos about measuring resistance (ohms) Walmart or a harbor freight should have cheap multimeters you can snag up.

I haven’t switched to a different type though, just been working on other things I suppose. \r\n\r\nGood idea about bridging. If you have a breadboard and/or some alligator clips you might be able to see an led pulse while you hold the switch down, but it might be too fast, not really sure. Seems like a good time to get an inexpensive multi meter though! \r\n\r\nFwiw, this is the one I got and it’s been acceptable.

I even just used it last weekend to test some stuff on my car. I’ve never changed the battery. I mainly bought it because it was cheap and well-reviewed on amazon.

I do not own the one linked but based on the reviews it can't be that bad for the price. and see what the voltage of the battery is, if it is above 11v I would consider the battery to be salvageable and try to recharge it. if not, yes I would get a new battery. Just know that while you are troubleshooting the bike that you should have a way to charge the battery. I used to just hook up leads from my car battery to my bike to do the testing; relying on the alternator of the ca to get the battery charged as I drove it. \r\n\r\nYes, a good place to start would be the battery, next I would test for spark: take the spark plug cap off, unbolt the plug, put the cap backon and ground the plug to the engine by holding threads up to the engine case (bare metal). and then try turning on the bike looking for small spark jumping at the tip. That should be good if he said it was running sporadically. then, again I would assume the carb is the main problem.","subreddit_name":"Fixxit","author":"Heath24Green"},{"body":"Thanks for the kind words.
