the one on the lh side is your starter relay and the other one is for your glow plug,to me it seems that you have a back feeding problem possibly caused by a faulty ignition switch which causes your starter to stay on after the key is depressed???.now this is just a possibility that you have 2 failures in a row(BOARD AND SWITCH) I STILL SAY TO START WITH THE BOARD! ,AS FOR THE SOLENOIDS,JUST TAKE THEM OUT FOR NOW AND CAP OFF THE HOLES WITH SOMETHING SO THAT JUNK CANT GO INTO THE HOLES,I`VE NEVER HAD A RELAY STAY ON AFTER IT HAS NO POWER TO IT SO I`M SURE IT IS NOT THE RELAY!!
