The 6a works. i'm talking about the coil.

If you are saying that you reconnect the old coil, then your ebay coil is intermittent. On the other hand, if you switch out other parts to get home, then substitute them one by one until you find the problem. Testing the coil when it is working won't tell you anything. It is probably opening up when it gets hot. In any case the ohm meter setting to test coil primaries is the lowest setting on the meter.

Yes. if i have blaster coil and 6a hooked up,it runs alright til i turn it off and sometimes it'll not start. When it does that,i will disconncet 6a and blaster coil completely,and i will connect back stock coil and amplifier.it then turns on every time.

Hook up the MSD system, run the engine until it fails, then do the spark test.

Either your trigger source is faulty, or the 6A module or the coil.

You're swapping too many parts at the same time.

Diagnosis does not work like that.

Checking the coil now.at 200ohm + to -,i get 0.8 and 0 for secondary. On 2000 ohm, i get 2 on + to -,0 on secondary.on 20k, primary i get 0, on secondary,10.15. On 200k,0 for primary,10.0 for secondary.2000k ,same as 200k. definetely bad coil?

[Gaz64]

10.15 k ohms on the secondary is a bad coil.
