Hi,

I recently purchased a Tenma-branded DC load which is really a Korad KEL-103 and which is not working.
After some quick testing, I am pretty sure the transformer is toast, but I am trying to confirm beyond any doubt.
Q1: As such, could someone with either a Tenma or Korad DC load please measure the resistance of the two primary windings (out of circuit)?
       Mine measure 41.4 Ohm and 4.6 Ohm respectively.
Also, the fact that there is no isolation between the two primary windings (again, out of circuit) makes me think something really bad must have happened.

Q2: Any chance someone could measure the outputs on the secondaries of the transformer (out of circuit as well)?

Q3: Any chance I can find a replacement transformer to purchase from Tenma or Korad?
       I've contacted Korad with this question (waiting for their response), but I could not find contact details for Tenma.

Thanks!
