Not being as brave as Vaultsman, I now have an RTC1372 fuse box kit in hand. Mine may be a bit different from his version, so I will add some observations re the interconnects on the part. Most leads etc are as he documented, plus:-
#3 feeds to a double sleeve which then leads to 21 and 23 EDIT-> this matches whats shown on the wiring diagram, but current fuse block does not have the same visible jumper lead. It maybe that the same effect is achieved differently?
#5 has a wire to #7, which has a copper bridge to #9 - no wire comes off 9!?
#11 has a copper bridge to #13
#15 has a copper bridge to #17 - no wire comes off 17!?
I have to say the plastic feels very hard and rigid, not what I expected from the pics of melted units. The sealed bag the unit arrived in is dated 01/08/79...
Next interesting point. Where there is a copper bridge from one point to the next, the bridge is from ONE of the two sides of a fuse clip to the adjacent fuse side clip - ie , looking at #7 from underneath, the left clip of #7 goes to the right clip of #9, and the 2 clips in #9 are not connected. Make sense? This means that a missing fuse can disable 2 circuits - eg if fuse 7-8 is missing, #9 will not get power
Also... on #1, with 2 brown wires coming off, I put a DVM on ohms on the 2 connections where the wires are crimped - zero; flex one of the wires away - open circuit. The 2 sides of the fuse clips are not connected unless the crimps touch, except by the fuse ends.
