Yamaha DT 125 LC 1985 - lights not working

[Keith H]

Hi, after 18 years in my garage I've decided to sell my beautiful bike. Starts every time and brake and indicator lights work.

New battery installed but can't get the side and head lights to work. I believe they are supposed to work when the engine is running?

The dash blue light (high beam indicator) not working so clerarly an issue which is beyond my knowledge.

Could it be the regulator or coil? Checked all cables for cracks etc.

Any help appreciated.

Thanks

Keith

do you have to turn the key to position 2 to gat the light working, as you do for it's predecessor the DTMX ?

[Keith H]

Only key positions are on/off so no. Thanks anyway.

[Cynic]

Sure. No park position.

Does the taillight come on.

[Keith H]

No to tail light. Tail break light works when brake pressed though.

I'm really thinking this is a regulator/rectifier issue.

Cant think what else it could be?

 

[Cynic]

Is the battery ok. If the regulators gone it will be fizzing like mad.

Otherwise the rectifier would be possible but i think the first job is checking the bulbs then cleaning the light switch.

[Keith H]

Batt is new, everything clean. Think I'll look for new or used rectifie.

Thanks for help.

Check the lighting coil, [ Ohms] 

[Keith H]

I've seen the coil but perhaps over looked that option, will investigate cheers

check the fuses, fuse connections - often it's the simple things
