Sinnis shuttle 125cc 17plate No hi/low lights

[Darrendavies]

Hi,
I have just passed my CBT and new to all this..... I purchased a Sinnis shuttle 125cc, 17 plate and when I bought it and looking around with the original owner I queried only 1 light on, he said that's what it's meant to be and 2 lights for full beam.... I bought the bike and a few days into driving it I noticed I had gone over a speed bump and the light went off and wouldn't come back on only the LED lights were on!

I went and bought new bulbs and fitted them to find this hasn't made them come back on..... a friend said maybe it was the switch so I've bought a new switch and fitted that tonight and that has made no difference.

The most confusing part is that when we checked the wires with a tester all wires are showing they're all OK and got power running from them.

I've even bought different new bulbs and they don't work, I've even put the original bulbs in and nothing....

I have come to a loss as new to this I've had a friend that's a mechanic look and he can't find the issue and I've had a friend who does electrical work and he can't get his head round it... all wires look fine no corrosion, breaks or anything

I've tried to Google, YouTube but can't find anything on a shuttle Sinnis.

Can anyone advise me please? Thanks in advance

Headlight relay?

e.g. -> https://www.ebay.co.uk/itm/324604068294

Or could be a short?

Expose all the loom wires. With the light turned on just wiggle everything around and see if it flickers.

Did you check for power or continuity?

They can't all have 12v on them. Some of them have to be earths. Basic electrical theory.

Did you do any science at school?

It isnt really a Sinnis btw,similarly to Lexmoto etc they just buy them from
ZHONGNENG VEHICLE GROUP in China or ZNEN
I doubt this will help you find a manual though and Sinnis wont be interested unless
you throw money at them

It's a ZN125T-8H ( if its EFI)
Product Name: Falcon 8 (in China)

A bump then the lights going out suggests a bad ground or connector shaken loose to me
maybe even a dry solder joint broken, a few minutes with a meter should locate the problem.
