Compression testing-gctid827192

[pgiconch]

I read elsewhere that once the plug wires (and plugs) were removed for compression testing the ignition coil had to be disabled or it would burn out trying to fire without the plugs connected. So I'm wondering if setting the "stop/kill" switch to off at the helm throttle would be sufficient, or is the only solution to pull all wires (+/-) from the coil?? Is there another solution besides these two? The engine starts & runs very well and I don't want to create a problem that doesn't exist.

BTW -- doing the compression check to determine if all cylinders are good due to previous overheat issue.

TIA

Thank you Bounty. It's been several years since I've done CC's (in the backyard on my MGA). A lot of technology changes since then, and just wanted to be sure, esp of the kill switch idea. I forgot to turn the KS on one day and cranked several times without a start and thought OH Gosh, what now. Then glanced down and realized it was down (off) and turned it back to on. Cranked right up. Plan is to "kill" the kill switch, and then pull the secondary out of the distributor and ground it with a wire to ground. "Overkill" perhaps but safe for Mr. Coil (and me). That way I wont lose any coil nuts fooling with the coil wires down to the dark void below the engine wherefrom nothing returns.

Thanks again.....FWFS
