Re: [DMCForum] difference between fuel senders

["Walter Coe" <Whalt@xxxxxxx>]

Enjoying a daze of low blood sugar, I took a look at a pair of boats and a spare DMCH sender.  Martin is right about the DMCH sender being a good deal for the money.  A lot more effort went into making it, and it is less than half the price of what SeaDoo charges.

What I don't like about the DMCH sender is their choice for resistor values.  They crowd them all around center scale while stretching out the top & bottom.  When riding in Mike Cohee's car to the Spring Social last year, at one point his gauge fluctuated between about 1/3rd scale to near empty.

Instead of eating breakfast and working on removing that hemorrhoid that the IRS has so graciously blessed me with (hey, I earned it) I stuck a meter on a spare DMCH sender and got the following values (in ohms from full to empty):

92.3
70.4
58.5
52.8
47.3
41.7
25.7
12.8
0.8

As you can see, they crowd all the increments near center scale.  Why?  Now I'm inspired to make my own senders, but I should really put the effort into making those sway bars and convex side mirrors.  I promise!  Now I need to eat before I pass out....
