Question about WPC fuses: Concerning the 3/8A fuses at F601 and F602. My demo man and shadow manuals call for Fast Blow fuses although the pinwiki WPC fuse jpeg shows slow blow? After checking, my shadow has SB's installed and has run for years no issue. On this demo man I installed FB as per manual and they blew. Which is correct?

I've also seen conflicting info for fuse F115 on the Driver board concerning the 3/4 A fuse as to if its FB or SB???

What are you guys running? thanks

Parts lookup (and parts lists linked on IPDB) says slow blow for every WPC game. Search on 3/8a.

Thanks! And if i'm doing this correctly I searched 3/4a and all games are fast blow? it doesn't say slow blow like the 3/8a search but it doesn't say F.B either?

my demo manual says s.b. while my shadow manual says f.b. ???

Pretty much everything in WPC games are slow blow.

I would put slow blow fuses on the dmd controller. Every game that I can recall working on were slow blow.

I think the manual where fast blow is noted is an error.

On another note, have you rebuilt the high voltage section on the dmd controller? That's really the best thing you can do for those boards. The aging original parts tend to put a strain on the dmd.

Didn't check the difference, but more games listed for 3/8a than 3/4a. I also don't see the usual 5 amp fuses for GI listed. Shadow is a WPC-S game and DM is a WPC (DCS), so not going to always match.
