Blinkers going mad ???

[LVC]

Hello,

I'm trying to fix a problem on a ZX50 for a pal of mine.

The blinkers/indicators make a horrible buzzing noise on tickover - if I accelerate up they then start to flash and then accelerating more and they go to solid (not flashing). Coming off the accelerator they slow down then speed up then go off.

The battery is very dead and the starter hasn't worked since he got it (inherited it off his older brother but has been sat for a good few years in his mum's garage).

I've tried reading the voltage across the regulator and it seems to be about 6v on tickover and then goes up to about 16v with the accelerator. I'm thinking that the regulator needs replacing - would I be right or is there something else that is causing this ?

Thanks in advance for your help

Suspect battery or flasher unit

I'm pretty certain the battery is dead - I'm getting no charging lights for it when I connect it to my Optimate 4.

Do these scooter's need a working battery for the indicators to function correctly? I've got several battery-less bikes and everything works fine on them without a battery (as long as the engine is turning). The headlights etc. all function just the brightness varies with the revs - guess it could be battery then instead of regulator.

I know where you are coming from. I had 50cc strokers back in the 80's that ran fine with no battery. Here's the thing though. If your battery is goosed, then your voltage regulator / rectifier is likely to be working its socks off trying to charge the battery. If the battery has a failed cell or is very high resistance, this may present itself as a short to the rectifier. Headlights that brighten with increased engine speed show that the reg/ rec is currently working.
That's good for a start off.
I'd start with a new battery bud. They are only £20/$30 for these little scoots

Thanks for the reply - I'll change the battery and give it a try

If not that then the fuse may be your problem, I also had a horrible buzz when the fuse was blown

Bad battery.
