Subject: Telrad not working; fix??
|
I thought that the Telrad was indestructible, but I find that mine has
suddenly stopped working. There is no apparent physical damage. I see that
there is no way to replace the light (led??). Has anyone had this problem or
could suggest a fix?

Are you sure your batterys are not dead? I had a wire brake once while
putting in new batters so I had to do a fast fix of that, but the only other
troubl I've had was the outside dimmer lever broke off when it was banged
once, but it's just fine even with just the bolt head sticking out and very
useable .

Wires seem secure and I changed the batteries. The thing worked fine a week
ago. I'll give it another check.

If you used aliy batterys they can go dead without warning, I had mine and
one time I setup and found that almost over night they had dropped down in
power, not enough to light leds, had to run across the street to the arco to
get some AA's to replace them with.

It's not likely the LED failed. Could be bad wiring (the wiring inside
is a bit amateurish- you should check it out), and make sure the battery
terminals are clean. Also, the switch/pot is a likely failure point.
That should be pretty easy to replace. Try shorting across it with
something and see if the light comes on.

Chris,
I'll give the pot a check. They must "go" because Highpoint Scientific
sells replacements for a few bucks. I'll also try cleaning the battery
terminals. I have some time to work on it now: a friend is going to let me
borrow one for Stellafane next weekend.

Probably a stupid question but have you tried a new battery?

Florian,
Ya...... tried the batteries. However, I didn't check to see if the
terminals are dirty. The unit got left on after using it last week.

You should be able to track down the problem with a simple voltmeter,
George. Hopefully batteries, contact cleaning, and/or a bit of soldering
will solve the problem.

I would also wonder if the reticle is ok as well.
It isnt hard to burn one out if the Telrad optical
window faces the sun for any length of time.

Right.....because of my own stupidity I've had to replace two reticles
over the past many years.

Sam, et al:
Well, I ordered a new one 'just in case', and two friends offered to let
me borrow theirs. THEN I found a bad connection on the battery holder box
that can be fixed. I now have *four* Telrads..... and a very strange looking
Obsession 20! :)
Look for Telrads for sale at Stellafane or Astromart........

I have one that goes between Babylon 8 and SG4 and that can be a pain as I
have to reline the telrad for each scope, and Galactica has it's own telrad.
Got to see how my bills go this month see if maybe a good pocket watch and a
telrad if nothing else.
Pocket watch I've been using died today.

Four Telrads?
Are Telrads like scopes -- you can never have too many and the guy who dies
with the most, wins.
