Problem- Power Spike?

[paul gibson]

Have a 2005 SL-20 that I suspect got a power spike from last nights storms.
As a rule I power down at the main every night. Must of been moving faster than I was thinking yesterday, and did not throw the switch.
A couple of years ago, I got spiked, and it blew one of the 1/2 amp fuses in the back. Replaced it and all was well.
Rear panel alarm this time shows problem in same fuses. Checked all with tester. All fuses were good. Replaced all with new fuses anyway, and still showing alarm.
Have some (FU1) elongated black components above fuse panel, and directly above the alarm light, that have what appears to be a screw driver slot in the back.
Look to be like an "in-line" fuse type affair. Anyone familiar with these?
Thought that possible they contained a fuse as well. But reluctant to dissect said same to find I was wrong.
Gentlemen, I cannot tell you how many storms I have powered down, and sit out, so I did not get "spiked".
And yet here I am. Any input appreciated.

Well, it seems when you get enough light, and a pair of glasses that you can actually read with.... The FU1 item mentioned in my previous post is marked as a fuse holder! Those dark areas and my eyesight! Once the fuse was replaced, all is well. Just a wee bit farther behind than I expected to be but, very thankful it was such a minor repair needed.

I could have been worse, you could have got one of these

Al,

The size of that spike and probably the bright flash it produced may have been easier for me to find the source!
Thanks for the chuckle! Turned out to be a lot better day than the way it started.

Regards

Fortunately you didn't drown this time.

To avoid relying on memory run the machine power through a magnetic contactor and power the solenoid via your lighting circuits; that way you don't need to remember anything except turn the lights out.

Of course it makes 'lights out' machining a bit difficult.
