Dt125 re not charging battary

[Calum]

@reecesloane-2017 It runs with a flat battery?

Must be generating power.

[reecesloane 2017]

Yes runs perfectly but brand new battary only lasted a couple days I thought it was the battary took it back and got another and that's done the same now all the lights work when running but doesn't charge the battary

[Zrako]

Did you checked all wires and connectors from generator to rectifier?

[reecesloane 2017]

Yes all
Look pretty good no damage that I can see nothing corroded bikes almost new so abit strange is it possible I'm ising the wrong battary I just got one that had the same dimensions and 12v ect surly it can't be that bad

[Mightyman]

@reecesloane-2017 generally, as long as it's a 12v battery it shouldn't make any difference so that isn't your issue.

[reecesloane 2017]

That's what I thought I'm stuck now electrics isn't my thing

[Calum]

@Mightyman little bit more to it than that bud. Obviously needs to be rated appropriately otherwise the engine will drain more power from the battery than the battery can supply. But the DT's could probably run off AA batteries lol.

[Mightyman]

@Calum aha yeah but generally people look into it much more than need be. "As long as it fits into the battery compartment" is my motto!

[reecesloane 2017]

So what would be the case now then where and how should I check any help
Would be great

[Calum]

I would be checking continuity between the genny and the battery terminals. It sounds like the engine is generating power enough to sort itself out, it's just a case of sorting out the charging circuit out.

[reecesloane 2017]

It's weird somtimes I think it may be shooting so where it has electric start and also kick start the other day I turned the ignition in and forgot the red on of switch so it was off but when I kicked the bike it was firing envelope a little smoke from the exhaust it wouldn't fully start but was 100% firing then die then I looked at the switch seen it was of turned it on and it started right up could this be an issue or is this normal thanks

I guess that could happen on a warm bike.
Before doing any more diagnostics regarding the battery/charging, you need a battery in good working order. You might be able to salve the current one, by putting it on a charger.

[reecesloane 2017]

The battary is brand new just went flat I'll charge it up
