SCR-3 Rotisserie

I was going to venture a guess that those 120v bulbs are connected in series.  Beings that it’s against my nature to NOT pry deeper, I did…and – they probably are.

With two good halogen bulbs working, pull one of them and see if the other light quits working.  If it does, then they’re connected in series.

 

I didn’t find a tech manual on the SCR-3, which has TWO lights.  But found a manual for the SCR-6/8, which has FOUR lights: http://www.hennypenny.com/wp-content/uploads/2014/08/SCR-FM06-011-Tech.pdf

 

It appears that Henny Penny mixed it up some in their light socket wiring.  Some wiring diagrams show sets of two lights connected in series.  Then other oven wiring diagrams have all lights connected in parallel (for 230v bulbs).  So it just depends on whether the oven was made to CE standards and is contingent upon the oven’s serial number for identifying which of THOSE requires 230v bulbs (like the parts manual shows).

 

I’m just wondering how you went about reading 208v going to them.

Did you test for that from the terminal board feeding the light circuit?

Or…

Did you take that 208v reading from an individual socket after removing its bulb?  If so…and if the OTHER socket’s bulb is still in place (with a good bulb), then you WILL read 208v at that open in the circuit (the empty socket).  Once you install a GOOD bulb into that open socket and take voltage reading across each individual socket where their wires connect, I think you’ll find that they’re only getting about 104v each.

Thanks EC

 

You’re right on the money. I knew I was overlooking something.

 

I was reading 208 on the wires going to the socket, but there was a burnt out bulb on that socket.

 

And now that I look at the schematic again they ***are*** in series.

 

Thanks for the help.
