Which tach are you talking about, the tiney tach or the gauge tach? It appears the TIney Tach is SLOW to respond which I have heard about them. I have a tach built in on my Trike and I bought a TTO tach and it responds right away the only thing it registers about 400 rpms higher than the built in tach so I do not know which one is closer to the real rpms(HAHA).

I ordered the speedometer for the BMS pathfinder. I will be installing it in my longbo. . My scooter does not have a tach.
So now it will need to be wired .

OK back to the game what's the problem with the all the time starting scooter?

The starter wants to run away from home.

what that would be is a bad solenoid

k let try this again he got the autochoke connected to the solenoid connector

I think the only possible thing is that when he was installing the Throttle cable on the Carb he Pulled a wire off.

Today i was installing my new carb and when i put the key in it just started to turn over. I removed the key and the switch and it still does it. so no that my battery is dead im racking my head to figure out why?
any suggestions? k let try this again he got the autochoke connected to the solenoid connector No that's not it buggin, autochoke only supplies power with the engine running and the solenoid has to have power. I think the only possible thing is that when he was installing the Throttle cable on the Carb he Pulled a wire off. Alleyoop Still not the problem of a all the time engaged solenoid. So he said after working on his carb and he stuck the key in it engaged and when he pulled it out it still was engaged. OK we all know that the starter relay gets 12Vdc from the brake light circuit when the brakes are engaged, either handle. That doesn't mean squat until you press the start button and supply the other side of the circuit to the relay the negative side. So while he was working on the carb it's highly likely he somehow got into the yellow/red wire (negative) on the starter relay and grounded it out, this happens. OK no big deal you say because he still has to press the brake to supply the other part of the circuit? Turning on the key which supplies the scooter with 12Vdc to the accessories (including brake lights and starter relay) should mean nothing to the brake lights until you press one which would engage the starter even without pressing the start button if it was grounded out. It was suggested that his solenoid relay has fused together a common problem and for sure that can happen but why all of a sudden did it do it when he was working on the carb, not a likely thing and these starter solenoid relays fusing together is not very common, in fact the most common problem with starter relays is just quitting. He asked for suggestions? Since this happened when he turned the key on then it's apparent he has a stuck (closed) brake light switch which would immediately supply 12Vdc to the starter relay upon turning on the key and........... he has upon working on his carb grounded out the yellow/red wire to the starter relay. Now he said it's doing it now even with the key out so that's a easy thing to check even without a multimeter in case his starter relay did fuse together when he pulled the key or his key switch and a brake switch are closed and the circuit is complete. (1) unhook the battery cable to the starter relay, charge the battery (2) unhook or pull the fuse on the red 12Vdc feed wire from the battery to the key switch (3) touch the battery cable going to the starter relay to the positive battery post, if it tries to start then relay is fused together and he needs to replace it and check out his wiring too. (4) if it does not try to start then hook up the battery cable to the battery and then touch the red fused wire to the key switch with the key off and see what happens. if it tries to start then he needs to find out which brake light switch is closed (bad) and replace the key switch. If it tries to start with the key off then the key switch is bad too. If it will not try to start with the key off then turn the key on and touch the red fused wire to the battery, if it tries to start then he needs to find out which brake switch is bad. He may have a fused together starter relay but according to him these events didn't happen until he worked on the carb and somehow he got the circle of events started while doing so which again was probably grounding out the yellow/red (negative) side of the starter relay. Lesson over you can pass it on to the interns who need your help.  JR

Even if the Brake switch was stuck it would not pass juice UNTIL YOU PRESS the START BUTTON. I still say when he was messing with the throttle cable the wire from the start button pulled out and is grounding out.

I still say when he was messing with the throttle cable the wire from the start button pulled out and is grounding out. Alleyoop Wrong. Pressing the start button sends no voltage. It only supplies a ground. He also said he was messing with the carb. Remember he said it would try to start with the key "out" thus the red/yellow wire = ground is touching a ground source. If you look a lot of times the starter relay wires (yellow/green & red/yellow) are easy to find in the carb area and it's easy to pinch one. If it came unplugged the way the plugs are made it would be tough to ground out just the end of the plug but's it's possible. If he pinched to ground the yellow/green then when he hit the brakes he would blow a fuse and have nothing. But if he pinches the red/yellow to ground he has done the same thing as push the start button. So if it will turn over with the key out then he has power all the time through the yellow/green and the red/yellow is grounded out. So it's very possible he has a bad key switch, bad brake switch and when he was working on the carb he grounded out the yellow/red wire thus exposing the first two problems he didn't even know about. Or he has altered the wiring on the scooter. JR |

While we are scratching our heads on this one, did you guys notice that there are some scoots that don't use the standard wiring convention for the starter circuit. Take a look at the Roketa MC-12-150 and Aruba diagrams. They run one side of the starter relay directly to ground.  The 12 volt feed runs through the starter switch which is in turn fed by the brake circuit. There is no switching on the ground side. A 12 volt short on the positive feed of the starter relay would be a lot easier to figure out without trying to work with a problem on the ground side. Hopefully he has this type of setup. So what kind of scoot does Random Hero have? |
