I consider myself a reasonable person and since I am just a tad younger than George Klass, tried to role with the punches of life but sometimes it's difficult to be reasonable. I have a 7530 MSD Ignition Controller in my race car. It's an older unit but it has always been in the interior and never exposed to the weather and very little time on the unit. I put a fresh engine in recently and when I tried to start the car is would not fire. No spark, checked all the connections etc. I borrowed an older 7-AL from a friend and it fired on the first revolution. I called MSD and was told to send it back for repairs which I did. They sent it back to me and said they could not find anything wrong. I went to a test & tune the next week-end and and made a couple of passes and the car ran great. At the track I replaced the 7-AL with the 7530 and again it would not fire. Changed back to the 7-AL and it ran fine with a couple of 9.75 passes. I called MSD and I was asked to do a couple of checks (cranking voltage on the small red wire & oms check). Batter voltage was 12.4 and cranking voltage on the red wire was 10.5. As instructed I checked oms resistance between the head and block. Less than 30 oms. MSD said all the checks were within specs and to send it back and this time they would replace the unit because it is their policy to replace the unit on the second return. I get the unit back today and they sent my old unit back and said they could not find anything wrong. I called the guy (Edgar on ext. 2234) and asked why it was not replaced like he promised and he said they do not make a 7530 and longer so they will not replace it. He said the 7530 was replaced with a 7530T. I said send me a 7530T and he said they would not. I argued because they did not tell me that before I sent it back. Edgar said he forgot to tell me about not replacing the 7530. He said it slipped his mind. Then he asked if I couldn't have someone else wire it in this time. Thats when I lost my cool. I told Edgar I am an certified aircraft electrician and I have enough phucking confidence in my ability to wire it correcty. I have over $100 in shipping and they basically said tough shit. The conversation ended with a couple of motherphuckers from me. I try not to let things get to me but damn. I have not used anything execpt MSD units. Are there any other brands out there that would be worth buying? I will not support a company that will not stand behind there product and lie to it's customers.
