[Vwdiesel] 81 Rabbit electrical woes

I'm having all sorts of relay/fuse problems lately - it all seems to
come down to a leak at the antenna which allowed water to get to the
back of the fuse/relay panel
several blown fuses, a short somewhere in the reverse light circuit...
but most important:
glow plug circuit is fritzing out
just did a quick diagnostic
I am not getting ANY GP action that I can discern at all, resulting in
VERY hard early morning starts
IF I wait more than a couple hours during the day, gets hard to start
with the entire GP relay bypassed, I am putting direct 12v to the bar
reading +13v at all 4 plugs
did this today early AM for 30 sec and still absolutely no effect
very hard start (i.e. 90 sec cranking - BAD for starter, etc
so how is it that ALL 4 GPs failed simultaneously?!
I am guessing that the rain to the fuse box somehow screwed up the
relay so that GP circuit stayed open continuously and all 4 burned out
can't account for it any other way
shouldn't putting 12v to the bus fire up those plugs?
but no dice!
anyway, I clearly need to replace the panel
in the meantime, I have new GPs + relay on their way
I am planning to bypass the box anyway and put a manual switch on the
dash - I prefer this anyway
but any thoughts on this situation?
looks like I need to remove IP to replace GPs
good idea to do a timing belt at the same time?
any feedback appreciated
