A new lamp produces no results, The ballast looks good
and has apparently not overheated. It is not open-circuited
There are two remaining components: The starter and
what looks to be a capacitor. I would strongly suspect the
starter, but can someone suggest a way to test the starter
before purchasing a new one? (They are about $40 for
this Hubbell 3V805A.
Thanks for your help!
In a very similar situation, I decided to take the obtuse approach first
and see if there was some remote chance that the new lamp I purchased
I exchanged it for another brand new lamp and it's been working fine
This was a 70-watt (I think) HPS using a Sylvania lamp.
There are testers for this purpose. But they will run you at least 40 bucks.
Have you measured the voltage for the output of the transformer? If not you
need to check this first. When I was re lamping a lot, 15 years ago. I
remember that there was 2 lamps to each transformer, and usually the starter
was replaced each time.
I suppose the starter should be tried first. I noted that the
lamp sometimes tries to ignite but the discharge only occurs
for a second or so. The capacitor seems to buzz as power is
applied to the circuit.
Is this a capacitor?
