the only thing i havent done is check the pickup coils resistence. any suggestions on how to do that?
From the Clymer manual,
Pickup Coil Testing
1. Remove the frame left hand side cover
2. Disconnect pickup coils 4-pin electrical connection containing 4 wires (1 b/y, 1 b, 1 b/w, and 1 b/r).
3. Set ohmmeter to R x 1000 and zero the test leads.
(My note here. These directions are for an analog meter. Digital meters don`t require zeroing.)
4. Check the resistance between the following wires in the pickup coil side of the 4-pin electrical connector.
a. Front cylinder: between the b/y and b terminals.
b. Rear cylinder: between b/w and b/r terminals.
Specified resistance is 355- 535 ohms.
5. If resistance is less than specified there is a short; if more the coil has an open.
In either case it must be replaced.
6. Set ohmmeter to highest setting and zero the leads.
7. Check resistance between each of the 4 wires in the pickup coil side of the 4-pin connector and chassis ground. Any meter reading less than infinity indicates a short and the pickup coil assembly must be replaced.
8. If coils check out OK, reconnect the electrical connector. Make sure it is free of corrosion and is tight.
(I suggest spraying with some electrical contact cleaner, dry completely and packing the male side of the connector with dielectric grease before snapping back together.)
9. Replace side cover.
(Someone here had a broken lead to the pickup coil and repaired it by soldering. Look out for that too.)
Hope this helps.
