Hello all. Trying to track down the cause of this issue on a Special Force. Looking at the manual, the coil tests that make the fuse glow/blow make sense. I skip a few tests in the menu because those ones don't do anything to the fuse. The knocker is what finally does it. The coil on the knocker is an A 26-1200, can I get confirmation that is the correct coil? Even so, as you will see, the knocker isn't the only coil that is giving the fuse a hard time. Any help is appreciated.

Would multiple coils make the fuse glow like that though? I will check out resistance.

It did it for every coil in that circuit. The knocker made it glow bringer and blew it on the 3rd or 2nd test.

The manual is pretty blurry, but it looks like that is what it says.

It's blown and been replaced several times trying to narrow down what what causing it. It is attached to everything shown in the image which makes me think it's pretty low value, but again, is what the manual calls for.

With my DMM, I'm getting 56V at the knocker and not 43V like the manual says. What I don't understand is the slings (supposedly on the same line according to the manual) are showing as ~44.5V, so not terrible. The previous video was actually with a .75A fuse. Not sure how that ended up with my 1A, batch, but it did. I put a 1A in there and now it's not glowing, but you can tell it's still being stressed. I made this video to show what happens when the right sling fires. It may not be glowing, but I still think something is off here.

Does anyone have an actual manual to say where the power comes from for this set of coils? The database one is a scan and the schematic is one of 3-4 on a single sheet. Zooming in is very blurry. Also, please see above post.

Much appreciated and thanks for the tip on checking SS manual.

Are there any guesses as to why the knocker was reading a higher voltage than the other coils?

I think I'm going to do this tonight and see if that eases off the 1A fuse as well for whatever reason.

Education time. I measured the knocker, as I mentioned. On the hot side (with the daisy chained wire) I'm getting 43V. I get the same 43V on both the hot and ground sides of both slings. I'm going to assume that this is because the diode bridges the lugs. But, on the ground side of the knocker, it's the 55V as mentioned above. I measured the J9-11 pin and I'm getting very low mV readings, so basically noise. Is that wire picking up another 12V from somewhere? Have some slo-blo fuses on order, so will undo the knocker and put the new fuse in when it gets here. I'd really like to find the source of the extra 12V though. I used the rail as my ground point for each test if that matters.
