QuestionHello i have a 1991 r/v series gmc crew cab single rear tire 1-ton p/u, 4x4, hydro boost, 350 tbi , OLD BODY STYLE automatic.
There is a 10 amp fuse in the block on the left hand row that keeps popping. It is labled ECMB and the wire for it is grounding out or the object that is attached is faulty. Please help me with finding out where the wire is going to and what the colour code is as it prevents the vehicle from starting and renders it useless.
I cant find any one who knows what EMCB stands for. Thank you for your time and patience, regards Shaun Welters,

AnswerHello Shaun, ECMB is an acronym for the vehicles brain unit. It's obviously grounding out like you have said. Check behind the fuse box where the wire emerges into a harness, look for any bald spots or burned areas.Also check hotwire off of altenator and starter, these are usually the culprits. Get back to me if you need further help.Also if you need parts at wholesale prices goto http://mywebpage.netscape.com/autoadviceguy/auto.html and click on a link or graphic to purchase parts.
