Sinnis apache electrical problems

[aj savage]

Hi everyone, I new to the biking scene so I don't really know what I'm looking at but i have a sinnis apache 125, i could have a full battery and no electrical problems but 2-3 hours later the battery starts to die and my bike goes really sluggish and bogs alot I don't have a clue! Can anyone help me please??

Sounds like your charging circuit. Before you start throwing money at random parts, get yourself a basic multimeter and measure the voltage across the battery with the engine off, idling and revving. You'll want to see about 12.5V, 13.5V and 14.5V (but no more than 15!) under those circumstances.

Okay that makes sense I'll try that, thankyou! Is it an object can I see the charging circuit? and is it easy to replace if that is the problem?

It could be your magneto/stator not generating any voltage, or your regulator/rectifier not making it usable. Best case, you could simply have a loose connection.

However, if you get yourself a multimeter and watch a few videos on how to use it, it will save you a lot of time and money in guessing. The good news is that parts for your bike are cheap and readily available, so it shouldn't cost a lot.
