Has anyone had a problem with their light speed only reading half the 

actual rpm?  I cut the plug off so I didnt have to drill a large hole 

through my firewall and re-soldered.  Everything worked fine for prob 

over 100 hours then I got the intermittent problem.  I had an 

experienced friend solder it for me and it worked for about 20 hours but 

is now doing it again.  Im probably going to buy a new harness and drill 

the big hole.  Anyone else have this problem?



Thanks

Shemp

Based on your careful look at the harness, recommend you assume the

LightSpeed box is bad and send it to Klaus.  I had a similar intermittent

Lightspeed LCD readout problem on mine before I removed the units.



I installed 6 Plasma II+ units on 3 RVs.  All the supplied wire harnesses

had cold solder joints.  I called Klaus and he told me that it was

impossible that his harnesses were the problem.  I sent them back to him

anyway and his short reply was "yea, these are bad".  I also did a field

repair of 5 of  the 6 boxes that had a wrong component on the board.  Again

Klaus told me my installation was bad until he actually looked at the box I

sent back.  He fixed the one box and sent me the components to repair the

other 5.  I didn't even get a thank you for identifying a problem with all

his shipped units, or for fixing the 5 I had for free.



After 450 hours and many more problems with my dual LightSpeed install

(including a totally failed unit in flight) I have removed them and am now

running dual P-Mags.  If anyone is interested I will provide the details of

my Lightspeed experience off list.

I'd be suspicious of the pins/sockets. If you are soldering then you are

probably using stamped instead of machined pins/sockets. Get a new D-sub

connector and the matching high quality, crimped <<machined>> pins/sockets.

I forget which one the cable has, just match the gender. You'll need a 4

point crimper but should be able to borrow one. You can always de-pin the

connector if you need to pull the cable through the firewall. The de-pinning

tool is a couple bucks.

What you want for reliability is the MIL-C-24308 series of D-subs that come  with M39029/XX-XXX type contacts.  The blue Daniels crimper is M22520/2-01  with the appropriate positioner.  Check the Daniels website for  applications.

Now Im wondering what to do.  I dont really believe the connection is bad but its the only thing I modified.  Im trying to find this d sub form the daniels website but so far havent been able to.  Do you think you could send me a link to the page?

 Thanks

 Shemp

 

 PS  Ive also found my egts to be very sensitive and sometimes erratic when the lightspeed is on.  Ive tested it with just the mag and they become pretty solid.
