Subject: [LML] Re: Gear Relays are not
working
My gear system was wired using the Legacy Wiring diagram.
By resistance I meant 0 ohms. The intermittant relays that were in the
plane originally were the ones that lancair sells on their website.
Now I have some continuous duty relays in their place.
So my next question is: If the Lancair wiring diagrams are wrong
and it seems that some of you out there have figured out a right way to do it,
why haven't you sent it to Lancair for them to update their manuals or at
least load it up on LML so all of us can get our aircraft wired
properly?
Maybe you can email me a copy?
thanks

No squat
switch. I built the plane and I did not put a squat switch in. On the good
note I spent all day yesterday retracting and free falling the gear and it
all works perfectly.

Bryan,
While the plane is on jacks, one test would be to open the dump
valve (relieve all pressure) and see if the pump runs in the gear down
direction, but not in the up. This would suggest that there is some
sort of "squat" switch. If so, the most frequently used one
relies on pitot-static pressure so the gear cannot be retracted until 70
KIAS is exceeded. Some simply bypass the switch with a jumper when
doing the gear checks while others may have installed a bypass switch,
sometimes hidden behind the panel.

My
lancair 360 was wired professionally. When we tried to do the gear
retraction tests.....nothing. We checked all the wires and made sure all
were getting power where they should. Checked the breakers, switch
etc.
We overran the relay and the motor ran so we figured it was a bad
relay......went to Napa and bought 2 new relays today. Installed them.
Same thing....nothing. Then we remembered that the relays were
mounted to a fiberglass bulkhead and the case needed to be grounded so we
attached a ground from the relay mounting base to ground bar.
Tried the gear.....now it worked...BUT it instantly fried the
ground wire on the relay small terimal......tried to measure the ohms of
the relays and no resistance....how could it be that I have 4 dead relays
all brand new?
So today I installed a Master Relay. The ones that are all
metal case. Now the gear works and no wires are getting fried........but
Im not happy with this result as it makes no sense why the normal relays
for this job aren't working....anybody have any ideas?
