I've been fighting with my scanner for the past week, and have finally

coaxed it into doing what it's supposed to do.  Consequently I'm trying to

get caught up with all the scans that need to be done to bring the

Attachments section of the LML homepage up to date.  I've started getting

the factory Service Bulletins scanned in, and have just posted copies of a

few faxes I received from Doug Weeldryer regarding the LC20 hydraulic pumps

and some notes from Jefco about ratios.  (These faxes were originally sent

to me by Angier Ames, as verifications of telcons between Doug and

himself.)  You can get directly to the Attachments area by following this URL:

While I'm on the subject of the LC20 hydraulic wiring, there was a question

here not long ago about the position of the gear switch and its

relationship to the terminals on its backside... someone mentioned that

they thought the lower 2 terminals should be connected to the low pressure

relay (gear down) and the upper terminals to the high pressure one (gear

up).  I checked the switch which came with my kit and found that if it's

wired as per the drawings (figure 14-17 or 14-17a), it will work as

intended.  As I suspected and mentioned previously, the switch end of the

bat handle sort of points to the two terminals that are closed, so with the

handle in the [gear] down position, the upper terminals are made.  With the

switch in the [gear] up position, the lower termials are made.  Once again,

be sure to check for continuity before final wiring, just to verify that

the switch is going to do what you expect it to.
