Here's my original grid heater contacts at 201,000 miles. They were replaced with Stancor 120-902 Power Contactors. I'm not sure they'd have made another winter in North Dakota.
NICE!!!!
They look shot. This is one thing I want to do, but seem to always forget about it.
I know there is a guy who sells the contacts, but cant seem to remember his name. Where did you get yours from?
