I turned the key to ON, and poked around: In any event, I put the alligator clip (surrounded by some unheated shrink tubing, lest it fall off and short something out) on the ground terminal on the fuse panel, the one with the beefy wire that goes straight back to the battery. I do have a test light/probe (but had been trying to be slicker, or something, to measure actual voltages). We have a real-world situation here that's seemingly beyond me.Īdditional tests, suggestions, anyone (excluding moving the bike to a corner of the garage and ordering an AK550)? I don't understand what's happening here.Īlthough I didn't have any problems with physics in high-school and first-year college, and an electronics class in the Army, my wife has accused of being BSO, which she explained to me means Book Smart Only. This puzzles me, because, as I noted - see item 3), above - there is not a lot of resistance in the connection from the starter switch to the headlight switch. (This was with the headlight switch in either position, which was the case with all my tests this morning.) If I take the black lead off the ground post and move it to the yellow headlight wire, the voltage is in the same direction. That is, with the key ON, if I measured from the starter switch to the ground post, I got a positive reading of, let's say, 13V (although this decreases as I play around, measuring things, without the bike's running). The voltage direction was that the headlight-switch wire was acting as ground. 12V across there - between the starter switch and that headlight-switch wire. Measuring from the starter switch (either blob) to the yellow (topmost in the pic above, pointed to by the green arrow), there was c. I found this interesting, puzzling, confusing, etc., which shows how much I know. With the starter button UNpushed, i.e., its resting state, and the key turned to ON, I measured from each starter-switch blob (the green arrows, above) to the ground on my fuse block (the post in there directly connected way back to the battery terminal).Įither blob test got me a reading of about 13V (on the meter's 20VDC scale).Ī) With the starter button UNpushed, i.e., its resting state, and the key turned to ON, I measured from all headlight blobs to that ground post, with the headlight switch in either position:ī) With the starter button UNpushed, i.e., its resting state, and the key turned to ON, I measured from all headlight blobs to the starter-switch blobs. From either point, I got about 13.6Ω (on the 200Ω scale).
