I just got a 5 ton dump truck (M51) and got it running after replacing th=
e
batteries. It ran great.

The brakes are not working although the compressor is making pressure. A=
ny
ideas before I tear into it?

Also, what does everyone do about the low air pressure buzzers? The
buzzer is so loud in this truck that you can't hear the engine crank ( or=

run for that matter) when the air brake pressure is low. I don't want t=
o
disconnect it but it is really loud! Any suggestion on how to quiet it
down?

Another question, this truck has developed a miss (R6602 gas engine) afte=
r
I dragged it on a trailer some 300+ miles through rain. It sounds like i=
t
is dropping spark to one or more plugs periodically. I thought the
ignitions on these trucks were pretty much water proof, but I think I've
found otherwise. Any suggestion other than start taking stuff apart to d=
ry
it out? It was running fine before I dragged it through several hundred=

miles of rain showers. =

Finally, what is the going price for those 6TL batteries. I haven't seen=

those at Sears recently, so I assume I'm going to have to buy them from
someone other than Sears or Sam's Club! Any good sources?

Thanks,

Dave =
