Re: [Healeys] Late Monday night rant.

[Bob Haskell <rchaskell@earthlink.net>]

When properly adjusted, the HF1748 horns fitted to the 100 - 3000 MkI 
are supposed to consume only 4 amps each according to the Lucas Workshop 
Instructions K-4.  So the 50 amp fuse for just the horns seems a bit 
high to me.  Wonder what they'll consume when not properly adjusted?

Cheers,
