Needs attention.

Just stripped down the siezed front brake on the 550, noticed the reservoir cap says Dot 3 only.

Can I use Dot 4?

Not sure I've ever seen Dot 3 for sale.

Have replaced the rectifier and regulator as the wiring was burnt out to the rectifier. Have replaced them with the combined solid state unit.

The field coil measures 5 ohms which looks correct and there is battery volts on the white wire to the field coil.

The three yellow wires from the stator measure about 1.0 ohm each which im guessing is correct if you take into account the resistance in the leads of my multimeter. Each of the 3 yellow wires also measure opent circuit to ground.

When the bike idles, im getting around 0.65 volts ac across any 2 yellow wires which is nowhere near enough.

Any ideas? im guessing the stator coil is fried but there is no evidence of any damage to it.

My wiring is a nightmare, especially the green earth wire which looks as like some heavy current has gone down it at some stage.

The green wire is earthed to the frame just by the coils. Is it earthed to the frame anywhere else?

Thanks.
