Posted: 21:08 - 11 May 2023 Post subject: stator issues, not charging, parts at fault |
|
|
I wonder if I can ask you guys a couple of things. I have a Suzuki Address 110, it's effectively Suzuki's version of the Honda Vision 110. it's 4 years old and little used, with only 1100 miles on the clock. I recently discovered on a long ride that the battery is not charging. I measured at the regulator, and one of the wires from the stator is measuring really low, I think I understand that they should be similar. The output from the regulator isn't above 11v, even when you rev the bike. my thoughts are that it's likely to be the stator. The bike is currently at a bike shop, they're busy, haven't taken anything apart, but measured the same voltages and agree with me, and are asking me to buy the parts. question as follows :-
1, Stator assembly consists of the part with the coils, and the housing/flywheel with the magnets on, I'm wondering which of these is likely to be the faulty part, not forgetting that the bike only has 1100 miles and probably came from the factory with this issue (it sits on a battery tender in my garage when not in use)
2, would the correct course of action be to dismantle the bike and inspect it visually before ordering parts ?
note : if two out of three phases of the stator have good output, does this in itself point to some issue with the stator coil part rather than the magnet/flywhee part ? ...... or could I even have an issue with wiring, faulty plug for example
my thoughts are that this needs pulling to bits, what are your thoughts ?
any advice, most appreciated
many thanks |

The stator is the static part (doesn't move), the rotor is the rotating part. So the stator is the part with a series of coils in a star shape. It may also come supplied with the pickup coils for the ignition attached.
The rotor is the metal housing with magnets in which rotates with the engine. These are much less prone to damage and it would usually be obvious if it was damaged by looking at it.
If it was me, I'd do a visual inspection of the stator, you can sometimes see scorching or damage if there's been a short on one of the coils. I'd also visually inspect the wires running between them and the rectifier.
I'd do a quick continuity test of those yellow wires (so between the coil and the rectifier) to make sure one wasn't damaged. Finally I'd check resistance between each pair of yellows (should be the same) and each yellow and the stator back plate (should be an open circuit).
If the stator windings are damaged, you will get inconsistent voltage readings between each pair of yellows. If there's a short to ground internally, you'll get a low resistance between one of the yellows and the backing plate. Either of those cases would warrant replacing or repairing the stator ____________________ “Rule one: Always stick around for one more drink. That's when things happen.
