'87 Aspy Charging Problems

Postby dutchwing » Sat May 31, 2014 12:11 pm

First my electrical mods: side saddlebag- and trunklights are leds. I have SEi markers on the sides of the fairing. Bypassed the original stator wires by 2,5mm2 gauge. Soldered to the stator and the filter on the other side. Bypassed the wires to the ignition and headlight as well (2,5mm2 gauge) directly from the battery (with solenoid and fused 20A). Changed the headlight to a Xenon H4. 4000 Mls ago changed my stator. The original was fried. Two weeks ago the voltage started fluctuating. Last week got 11,6 V max. Checked the output: 14/16/14 volts AC, should be at least 54 volts AC. Bought a new stator and rectifier. Gonna take out the engine next weekend. The question is: does anyone have an idea on why my new stator got fried aftef only 4000 Mls?

When you changed out the stator the first time did you replace the rectifier/regulator? It's always a good idea to replace both of these units together.
The stator max current output is about 30 amps, if you exceed this then damage can happen to both the regulator and the stator, this may not show up until a few miles have been put on the bike, due to the excess heat slowly breaking down the insulation on the stator windings.

Check you amperage requirements of the bike and all the add-ons, make sure you don't exceed the supply current.
