mouse 6 Posted May 4, 2018 Hi Gang. For a while now I've been having trouble starting my Mk.1(1600 crossflow) I've tried different batteries on it and after a few seconds the starter motor runs slow.This starter is supposed to be remanufactured.. Now,I have a clip on ammeter. When I put the ammeter on my mates car the reading is 200 amps. When I put this ammeter on my engine it jumps about but reads about 400 A. Can any Gure out there shed any light on the current draw figures of this setup?? Regards Mouse.. Quote Share this post Link to post Share on other sites
John Mack 336 Posted May 4, 2018 When I put the ammeter on my mates car the reading is 200 amps. When I put this ammeter on my engine it jumps about but reads about 400 A. If it's the same car/engine.....I think your engine has a lot more compression !!........or it's seizing up? Quote Share this post Link to post Share on other sites
Tony Webster 32 Posted May 4, 2018 Sorry I don't have any spec's amperage wise, though I can offer a suggestion and say the motor may have a "short" in the armature or field windings ... All that current going straight to earth ............ :wine: Quote Share this post Link to post Share on other sites
mouse 6 Posted May 4, 2018 Hi Gang. I think the suggestion about a short in the wingdings is probably correct. The next thing is to try another starter motor.. Regards Mouse.. Quote Share this post Link to post Share on other sites
Barnstormer 7 Posted May 5, 2018 (edited) If the starter is getting very hot in a short space of time it's looking like it's got a serious problem. I had the same problem with the starter running slow. The soldering in the windings had started to break up / melt. I overhauled it myself with a new armature - never had a problem since. Fairly easy job to do. Edited May 5, 2018 by Barnstormer Quote Share this post Link to post Share on other sites
mouse 6 Posted May 5, 2018 Hi. Yes it's looking like the starter motor.. Regards Iain.. Quote Share this post Link to post Share on other sites
MK5 V8 1 Posted May 31, 2018 yep deffo the starter, if it was remanned then it wasn't done very well, probably a short from the field coils to the body Quote Share this post Link to post Share on other sites
mouse 6 Posted May 31, 2018 Hi. Thank's for your reply.. I checked the field coils and sure enough there was a dead short. I'm looking for a body for the m35j. Regards Mouse.. Quote Share this post Link to post Share on other sites
Tigdlo 27 Posted June 1, 2018 Worth checking that the engine is properly earthed to the battery. Also, that the motor is bonded to the bellhousing. You say that it’s a refurbed motor, so check that there isn’t paint between the motor and the bellhousing. Quote Share this post Link to post Share on other sites
