I was under the assumption that it wouldn't turn over at all if the CPS was bad, but I've been wrong a time or two in my short span of 20 years on earth. Thanks for the help! Will post a conclusion if the replacement solves problems. If not, I'll be back for more questions! Also, I know they are affected by heat.. so what can I do to keep heat out? My dad suggested a starter wrap or heat reflective tape.
