Todd/Honda problem [RE-wrenches]

[jay peltz]

Hi David,

I have had a lot of problems with the "new" todd 75's running in series. When I worked at AEE we
burned up 8 or 10 of them running in series, and this was on utility power.  I don't know the answer
to your question but I would caution you to use the 75's, the 45's and 30's seem to be fine however.
