New cable installed - same problems with turn lights. By bobf (Read 1,113 times)

[bobf]

Installed new cable today and found that nothing got fixed. I still have flashing turn lights. Now I am wondering if my wiring of the volt meter is causing this problem. So I will disconnect that wiring and see if the problem corrects. If not I have to look further to find the problem.

Any ideas what might be causing the probllem of the turn lights staying on with LEFT TURN light, RIGHT TURN light, or both LEFT and RIGHT lights flashing and no way to shut them off..

The turn signal switch is a source for this problem along with a bad signal flasher module.

Thanks JR. I was just playing with the wiring and came to a similar conclusion. So now I guess I will go to the parts book and try to find the item I should be looking for. So if the switch was not bad I should have just swapped out the signal flasher module. Just not thinking ahead very well.

[bobf]

OK, I have been to the parts pages on Roketa forum, but did not get a definite description or part number to order.

Anybody know off hand? Or I could maybe just ask the vendor that sold me the new cable might know what part I need and where it is located.

With my dummy-level electrical understanding: when electricity is allowed to go to the turns or flashers, which normally occurs via the handlebar switches, it first passes through the flasher unit, which interrupts it periodically, producing the on/off behavior. Without further checking my YY250T wiring diagram, I would think the path is source --> flasher --> relevant switch --> relevant light(s). As long as the switch is not on, the flasher just sits there doing nothing, since current is not flowing. If you are getting flashing behavior, even unwanted, then I would think the flasher unit itself is working as intended, but it's somehow getting juice from another source.

Ergo, it sounds like something you've done with the wiring is allowing electricity to find ANOTHER path to the flasher unit and then the light(s) in question. But I'm not entirely clear. Is it doing this weird thing only after you have energized the appropriate switch on the handlebars? And then it won't turn off? Or is the flashing happening as soon as you turn on the ignition? Or what?

BTW, when I installed my dashboard voltmeter, if I recall correctly I ran a wire direct to battery+ as source, and the other wire direct to the frame. If you tapped into some other 12v wire as a source, that'd be the first place I'd investigate.

[bobf]

Thanks ellpee, I tapped power and ran black wires to frame. I did remove the tapped wires but nothing changed as far as the blinking. Next, when I get time I will remove the ground wires to the frame and see what happens.

A bit short of time these days as my wife is in a rehab center for her heart attack near two weeks ago. She seems to be doing well in recovery unit.

I will try later today to remove those last wires I installed. Then I will see what happens. Basically I will remove and reinstall, while reading the instructions, and then see how it goes. I may have somehow crossed things up.

[ellpee]

Okay, well, it may be clear to others, but not so much to me. SCENARIO 1: With ignition switch already on, you turn on a turn signal, or the emergency flashers, using the handlebar switches, and they go on but then won't turn off using the handlebar switches, as should be the case. SCENARIO 2, you turn on the key and start getting flashing lights without touching anything else, and with no way to turn them off except to shut off the ignition switch..

Don't let all this distract you from Priority 1, which is wifey's recovery. Scootering is great, but doesn't in any way trump the important stuff in life. Best wishes.

[bobf]

Eelpee, your scenario 2 is the way my scoot operates. Turn the key and the lights start flashing.

I never got time today to finish removing all wires I added. If my removal of all wires I added fixed the blinking lights, then I know where not to connect again. So it will be a complete restart of wiring after that. With step by step checks for unwanted activities.

One thing for sure, I am somehow after the switch, which is good.

[ellpee]

Yup, sounds to me like wherever you connected the voltmeter to 12v, somehow or other 12v is also going to the flasher circuit. Not sure how that could be, but wiring the voltmeter directly back to the battery or fusebox would be a good idea.

[bobf]

Thanks ellpee, right now I have no wires connected to the voltmeter, all wires have now been removed and nothing but original wires now in the machine. Wondering now if I did something wrong when I reworked items earlier this spring. So now I go back to what was I doing before and what wires were I messing with. I should have some notes on this forum from back winter and spring time. So that is where I will start my back tracking. I know I replaced the charging system parts, what else?

[bobf]

Well I do know that at times I have had covers off and returned. May have somehow connected a pair incorrectly.

Seems like my only way to chase this problem is to have the lights on and then disconnect and reconnect until I see the problem go away and come back. Then I will be close to fixing the problem. I know that I had the back covers off and also the front covers. Closest to the problem should be the front covers and cables.

First, I will be going to Colorado starting Sunday morning and be in Cortez Colorado late afternoon. I should be back to Casa Grande AZ by Friday night for sure. Then I will report what I find after I get time to work on the scoot.

High technology in this 'seek till you find' operation.

Any one have a good electrical schematic for the vertical engine scoot, MC 54-250?

[ellpee]

I have one that has proven mostly accurate for my 2011, but don't remember how to attach a file here. PM me your EMail and I'll send it to you. I believe I got it from this forum in the first place.

[bobf]

Digging in my files I have found a hard copy of a circuit diagram. Hand written note at top says "MC-54B-250".

I have been tracing wires on it and will start following them when I get back from Colorado.

[e-mail]

Yours may be more accurate so I will compare them.

I do remember not too long ago I changed out the regulator/rectifier. Possible source for voltage wiring mix up. Something else to check on when I get back from Colorado.

[ellpee]

Mine is on the way, maybe better, maybe not. Best to you and wifey.
