[DMCForum] Re: Testing Frequency valve

["cruznmd" <racuti1@xxxxxxxxxxxx>]

Make a jumper out of some scrap wire, (3-6 in. long) crimp a male 
spade on each end (flat metal piece) and I -THINK- contact 38, and 
80. The book doesn't say which ones to jump for the freq valve, only 
the fuel pump.

I leave for home in a few minutes. When I get there I will jumper it 
and post which terminals to jump here.
