Thank you hooligan for your reply. I should be more specific in my post.
When I turn on the Power Gear leveling system, the lights flash in a pattern that indicates that the trans in not in neutral (diesel) the system will not activate. Also I may have to turn the key several times before the starter will engage & start the engine. I was wondering if there may be a common reason for the two to not work & I was told to check the 'neutral safety switch'. It might be called something else. But I don't know where this switch/relay is located. Or else these are 2 separate problems that happened at the same time???
