i lost my turn signals By 95sunfire (Read 703 times)

that's how it started,now I'm lost...lol the relay would buzz but no blinking,so i went to auto parts store grabbed a 12v flasher nipped the wires off my old relay added a couple connectors hooked it up and nothing. getting frustrated i got online ordered a new relay and got a switch while i was there,parts arrived new relay nothing, tried switch still nothing. started reading through library here and doing some testing, then the questions began bouncing around in my head (lots of free space i guess) enough history lets get to the facts.

2006 wildfire 50cc 4 stroke
372 miles at time of purchase
battery was dead when i bought it previous owner said he tried charging it but it wouldn't hold a charge never messed with it after he just kick-started it and everything worked so he didn't worry about it.

Checked black wire going into relay 6.5v
gray coming out 6.5v roughly
these being low i started looking around
started checking regulator
white at idle roughly 35vac will rise if the engine is revved
red 6.8v dc
green 0 assuming this is ground
yellow 2.35v dc
all tests are with engine running as battery is still dead,have a new one just don't want to install till i get charging system working.

Questions can i assume regulator is bad? what should the voltage at the white wire be? yellow? is there anything I've missed ?

PS i checked the switch i have continuity through,bulbs are all good,signals worked before if i left the engine run for awhile they would start working then just quit altogether, previous owner mentioned they tried to jump start it once with a car (he couldn't remember if it was running or not)

Easiest way is to put the new fully charged battery in the scoot, then when the scoot is running, measure the voltage between the positive (red) and negative terminals on the battery.
Should be about 12.5-13 volts at idle. Put the lights on and voltage should stay the same, rev the engine and voltage should go up to about 13-14 volts.
If you have that then the charging system is working within limits. If not then you can start looking for the source of any problems.

Good advice from Robo63 on the battery, that will also give you some insight into your regulator as far as the red wire. The white and yellow should give you roughly 12v AC hooked up to the regulator. Just touch one probe of the multi to the wire and the other to ground. If the voltages you listed are correct you need a new rectifier/regulator. Rich

ok i now have turn signals, yay! new battery fixed problem, rechecked wires at regulator all seem to be right now, with wire hooked up 11.8vac on white, 12.2vac at yellow,13.2vdc on red same at battery from terminal to terminal, rechecked my homemade relay pigtail with flasher robbed from my truck works great,checked original by touching wire it still works, but the replacement i bought online doesn't (wire colors are different blue,red,black not sure if that matters)nor does the aftermarket one i got from auto parts store(i might know why it says electronic flasher on package) i tried it in my truck and it blew a fuse so it may just have been junk to start with.

While experimenting i found out my electric start doesn't work, so i guess i'm not quite done yet

forgot to mention i know my idle is a little high (turned it up a bit to keep it running for test ride) thus the reason for higher than norm idle voltages, i'm still trying to burn up the remaining fuel left from PO he filled it the day i test rode it,i'm currently at about 55miles and have barely put a dent in it. damn thing gets too good of mileage...LOL
