[DMCForum] Re: very frustrated!! - starting problem



Thanks for all the info!  Here's my situation thus far.

I have a full tank of fuel.  The sender is not working properly.  It
shows a half tank of gas and I know it is full.  I did check the
sender outside of the tank and it does respond to a dry test. 
(Perhaps the floater has a hole or it is too weighty?)

The rpm relay looks fine actually.  It is black and the contacts are
clean and straight.  I wouldn't mind sending a pic so I know that I
indeed am checking the correct thing.

NOw for the volt test.  I checked it and when the ignition is turner
it jumped for a split second to 7-8 then back to 00.00  This may not
be entirely accurate becasue it only flashed a charge for a split
second and so I may not have read it right.  This tells me that
perhaps a relay is bad or the ground is not good (am I on the right
track?) My ground is attached well to the pump but I re-did it again
anyways.  I looked in the relay compartment and I found that a good
number of fuses were mismatched with the wrong numbers!!  So before
I do anything else I'm going to make sure everything is in stock
order as far as I can tell so I can rule out any funky electrical
mayhem in the compartment.
By the way - the battery is charged at 11.8 or so...

stupid question... where is the inertia swtch?

thanks again!!
