pick up coils

well I need a set for my 83 royal. tested connector on left side just like two not there no meter movement the other 33.9 there is only one 6 gang connector with one left blank.

well I need a set for my 83 royal. tested connector on left side just like two not there no meter movement the other 33.9 there is only one 6 gang connector with one left blank.

 

On the six pin connector, there is a blank space, wire above that space is common to all 4 coils. It is black, but often difficult to see color due to somewhat dirty conditions in area where connector is situated.

 

There is also another 6 pin connector in same area which is for gear indicator if your bike has a digital gear indicator. This on has all 6 pins used. I don't think the 83's had this, but it could have been modified in the last 31 years.

 

With one meter lead connected to black wire, then check each of the other 4 wires. Reading should be between 93.5 ~ 126.5 ohms each. My personal opinion is it doesn't matter if reading is to high or low end of range as long as all 4 are consistent.

 

Next attach one lead of meter to clean frame ground (or negative battery terminal) and check each of the 5 wires for any continuity to ground. Highest ohm setting on meter preferable if it is not an auto range style meter. Reading should be infinite (not 0 or near) on any wire to ground.

 

This is starkly different than procedure for testing stator coils. But that is not your issue, so I won't muddy the waters with that. Just threw that out there since both components are in the same area and wires exit at same point.

 

I do have a couple of sets of pickup coils if you are sure that is problem, but it is a job to replace them. Both left side motor covers need to be removed for access. Both will need new gaskets.

 

Also look at contact mating surfaces on 6 pin connector for dirt, grease or corrosion. Also check connectors on TCI plugs for dirty or corroded connectors. 6 pin connector on TCI is one that pickup coils feed into. You can also check ohm readings at TCI on cable end of the 6 pin connector. Do not take resistance readings into the TCI itself. On the 6 pin TCI connector, all six are used. The Black with white tracer wire is not involved with pickup coils. Use black as common again.

thank you. I tested it the correct way and all is fine with it. so that leads me back to carbs. the other site had a nice tec article for rebuilding. I am worried cant get two drain screws loose no drive head left on them. will they survive when torn down. going to set down and memorize as much as I can
