This is a real "duzzy"<br />A 1997 Mercury OB 150HP Model# 1150422TD <br /> Serial # 0G530666<br />This engine cold starts fine and warm starts fine most of the time but sometimes:<br />After it warms up and is turned off, then you attempt to restart it there is no reaction when the key is turned to the start position. It reacts like the battery is totally dead - which it's not. <br />Other pertinent info when this occurs:<br />1- You can try starting it again and sometimes it will start and sometimes not.Eventually it will restart.<br />2- Gauges all fall to zero when the key is turned to start.<br />3- All guages go crazy after restart.<br />4- Ignition switch, kill switch, engine control, including neutral safety switch and battery are all new.<br />Please help with this gremlin - we are at our wits end trying to solve this problem.
