Starter heat soak FYI

[eightbanger]

Well my Ebay starter packed up after 4 years, heat soak from the headers was the prime suspect, I replaced it on recommendation with a Powermaster starter, a more pricey unit but was assured the short life of my last starter would not be repeated. Now 2 mths down the line I began having the same problem, slow engine cranking, and after a long drive little or no cranking at all until it cooled a bit, so back to the shop for a replacement, but this time I purchased a heat shield and clocked it closer to the block. I dropped the tech guys at Powermaster an email mentioning the heat shield and they told me "do not add any heat shield to their starter as this would cause heat soak" and my problem was most likely caused by a fault in the ignition not sending 12 volts to the starter. I have tested the ignition lead while removed from the starter and it registered 12V, then tested it while connected and got 6V, so there does seem to be some electrical issue affecting them rather than the heat from my headers.
