pickup coil s3 xj6
Im suspecting a non start situation ( no spark out of coil, 12v at both +ve and -ve coil posts with ignition on )
is due to a faulty distributor pick up coil.
Does anyone have an aftermarket pick up coil part number?
would hate to pay jaguar prices, hey sell it witht he plate which i dont need.

BTW, i understand pick up coils can be purchased with out the metal plate... anyone have those part numbers?
Dougs numbers are asolutely correct and appreciated (thankyou doug!!), but there hitting $200. I read somewhere some one just replaced the pickup module,, it was way cheaper

Checking resistance as you mentioned is the only test for the pickup coil.
However.....
Here's a diag tree for the CEI system.
The test assumes a fully charged battery
1) Measure voltage at coil "+" terminal with key "on". It should be within
one volt of battery voltage. If not suspect a problem with the wiring to the
ignition switch, or the switch itself.
2) Measure voltage at the coil "-" terminal. Result should be the same as at
the "+" terminal. If Ok, go to step 3. If not....
Disconnect the wire from the amplifier from the "-" post of the coil and
measure voltage again. Less than 2 volts means the coil is faulty. More than
2 volts means the amplifier is faulty.
3) Disconnect distributor pickup coil from the amplifier (this is the
harness from the distributor that plugs into the amp). Measure resistance
across the terminals. It should be 2.2k to 4.8k ohms. If Ok, go to step 4.
If not, replace the pickup.
4) Reconnect the pickup to the amplifier. Measure voltage at coil "-" post
while cranking engine. The voltage should drop. If OK, go to step 5. If
not, the amplifier is faulty.
5) Check distributor cap and wires, distributor rotor arm, spark plugs, coil
wire
