I managed to fry the fuse on the BTK. Um, BIK, um, that thingy that the charger plugs into.
What size fuse is it?
Depends on the BIK.
If it is a BIK-TC5 it is 5 amps.
Tony, should he not check out his wiring before just sticking a new fuse and powering up? I sure would, fuse is a sftey device and will go before a board goes!
Hi Paul.
Perhaps he should but it depends on why the fuse blew.
Tony, it blew because there was an excessive current!!! And just what would cause that, pray tell?

Ol’ Stupid here threw the switch in the SD-45 from battery to track without disconnecting the battery car or turning off the BIK. There was a sudden influx of 18 volts at 10 amps. The fuse worked as designed.
Thank you Steve.
Brain fade can happen to any of us. 
The trick is owning up to our mistakes.

Brain fade?
So it wasn’t a senior moment? I’m so relieved. I thought I was loosing it.

OK, so I finally found a fuse of the same physical size, a 5 amp, 125 volt fast blow, sold for Christmas tree lights. I guess that will work? The others were 'way expensive, designed for microwave equipment.
If it is the same physical size and the same amperage rating then you are golden. Voltage is irrelevant on fuse ratings.
