[mit]

help some one. i have to charge my d 1850fd tractor everytime i want to start it. the charging light goes out but it is not charging. how do i fix it. the belt is tight the battery volts is 12.67. when the engine is running the volts drops to 12.65. there is no regulator.

Sounds like alternator is bad. Also, you might have a short somewhere, pulling the battery down. Remove one of the battery cables (with engine off), then clip test light to cable, put probe on battery post. If light lights up, you have a draw somewhere.

Test it from the back of the alternator if possible...if still not charging you can remove and take to auto parts store and see if they can test it for you to get a second opinion to confirm it is bad.

does any one knows if there is a regulator that controls the charging?could this cause the problem? if it is what symptom should i look for.

My 372 has a seperate regulator located under the instrument cluster. A regulator will do just what your experiencing or the alternator will cause it.

i found the regulator. how do i know if the regulator is not causing the problem. i could remove the alternator and take it for a bench test but the last time i did that they said the alternator was bad and had to be rebuilt. when i brought back and installed it it still did not work i found a broken wire and when i put it together it worked.so i want to make sure before taking this one out.

ok it is the alternator i checked the regulator and it is good. have to get this thing rebuilt. found that the rectifier cost 350 dollars.the rebuilt alternator cost 250.a savings of 100 dollars and u dont have to open it.does anyone know where to get replacement alternator parts cheaper.

i looked into the alternator for the ford courier 1972 it is such a close match that i bought one. the bolts do not match up to get it to fit normal with the existing bracket. the connections match up perfectly.well what do i do?here is what i did: i went out and got two, two inches metric bolts with washers. then i hooked up the wires ,flipped the alternator around and bolt on the adjusting hole on the bottom. then i put the other bolt through the hole on top and use a nut to bolt it on.the bolts sticks out a little.it does not look pretty but it puts out 13.5 volts. the cost about 60 bucks.i took some pics :

managed to put up the images. the adjustment on the alternator is maxed out. this could be a good temporary fix i think. any one care to make a comment? the pics were taken with the enging running.
