maybe someone has fixt this problem,. and can coach me , my 750 massey has electric hydraulics ,,. when it worx ,,.,. all thelite ups on the overhead go out after about10 seconds to 5 minutes of running , I was suspecting the little silver solenoids undr the console not sure what is the cause ,. talkt with my local massy man , he thought it could be the oil pressure sending unit , he asked if it was lit when electronix worked and the overhead lite is lit indeed,oil level is on the full mark . he also told me how to override it,if my sending unit had 2 posts ,, but it only has one post ,.I also mentioned that during our fuel injector ans turbo woes 2 yrs ago we removed the kill plunger on the murphy switch and have not reinstalled it ,.he was not sure if that was workin against me , but it mite be , so I will try that tomorrow ,.
