stef123 Posted January 12, 2013 Share Posted January 12, 2013 Have you measured the resistance of each plug? Quote Link to comment Share on other sites More sharing options...

john34 Posted January 12, 2013 Author Share Posted January 12, 2013 Hi Thanks very much for the diagram it's very good but I have Haynes I needed ford diagram as Haynes is a typical and not the same But thanks for that I have tested resistance on plugs with multimeter Continuity test and it comes up 0.6 ohms that's each plug out the engine I have put them back in and put rail on but took the poss wire off rail and put fuse back in And it has not blown so it is the rail I have used a wire with 20 amp fuse and put from poss Of battery and put it to the rail and it pops the fuse So some where its going to ground How can I test each plug as they all glow nice when each one is put to the battery Thanks a lot for your help John Quote Link to comment Share on other sites More sharing options...

stef123 Posted January 13, 2013 Share Posted January 13, 2013 Im sure Haynes quotes something about each plug drawing about 15A? Ive still got my old set from the 2.2 that i could measure to confirm this for you - both engines probably use the same plug anyway. Quote Link to comment Share on other sites More sharing options...
john34 Posted January 13, 2013 Author Share Posted January 13, 2013 Hi Thanks for your replys it all sound true and good but my car did work and Haynes engine fuse box F8 and ford have it as a 60 amp slow blow so it is right I have taken them all out and rail off Tested each plug on battery with 20 amp fuse and all work no problem But am I right in saying if they are all in and I put my 20 amp wire on the rail the fuse should not blow but the plugs won't work because they don't have enoght amps to work I have brought a new glow plug to test it's ohms and that is 0.8 So does any one know how to test these plugs And where are all the engine earth straps so I can check them Thanks a lot John Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 13, 2013 Share Posted January 13, 2013 0.8 ohms @12V would theoretically work out to 15A a plug - which is correct (given the 60A fuse) with all 4 plugs connected to the rail, they will blow a 20A fuse - the fuse is simply an over current device. it does sound like 4 new plugs will solve your problems though Quote Link to comment Share on other sites More sharing options...
