I hope someone can help me out here. I want to get a turbo timer (TT) for my 96 CTD. When I go to ebay, you can get them from about $30+ but if you put diesel in with the search they go to $150+ do I need one made for the diesel? The way I understand it works is that when you turn the key off the TT maintains 12Volts to the fuel shut-off. Now I know that there are two relays in the system the one that opens the shut-off takes alot of amps to work but the one that holds it open does not and I think thats the one that the TT would work with. So I'm thinking you don't have spend the $150 for the TT on the diesel. If I am wrong aout this will someone set me straight.
