screwed alternator and rev counter problem... HELP!

[GoLfMan]

started the mk1 up today and took it for a drive with its new suspension in it handles brilliant but the engine didnt feel that fit for some reason and when i got back smelt a burning smell.... the alternator had gone and sapt all charge from the battery while it was at it!

also my rev counter was acting weird! bouncing up and down like a yo yo whats wrong?!?!!?

[ontarv]

if alt died rev counter would play up
as your bat drains, less power gets to coil
and eng power drops due weaker spark and signal
for taco comes from coil so can get wacky!!
vn commy alt fit in without to much hassle thats
what i run, 85 amps as well !!

All probably down to the alternator at this stage. Get that sorted before chasing any other snags.

Keep in mind that the alternator output may have gone way over 14volts and fried a few things too.
