SWB Posted March 3, 2018 Share Posted March 3, 2018 Series III petrol, 2 1/4 petrol, when starting engine the starter motor turns very slow, as if the battery is flat. (New battery fitted). Wiring fully connected, nothing missing or loose. Anyone any ideas?. Quote Link to comment Share on other sites More sharing options...
rtbarton Posted March 3, 2018 Share Posted March 3, 2018 Can you feel anything (connections &c) getting warm? Cold thick oil? Quote Link to comment Share on other sites More sharing options...
lo-fi Posted March 3, 2018 Share Posted March 3, 2018 Knackered brushes or a broken spring. They're easy enough and cheap to replace. Could also be it's just partly seized and expending a lot of effort turning itself. Pull it out and give it some TLC. Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 3, 2018 Share Posted March 3, 2018 I have just been through something similar in these cold mornings. The 88" was terribly slow on the starter and I had to give up on starting a couple of mornings. But as soon as the Sun had been up a couple of hours (still below zero though) it would fire right up. And it didn't matter how good a battery I hooked up. Turned out to be the gap in the points! Had to look back at my old teachings about points ignition and the ramping of the ignition to realize that because the gap was too big the ignition happened too fast and therefore too early so the starter couldn't crank it over. Why it was worse when really cold I don't know, but maybe because the air is denser. Maybe this is your problem as well? Could be worth checking before swapping out the startermotor Quote Link to comment Share on other sites More sharing options...
Snagger Posted March 7, 2018 Share Posted March 7, 2018 A new battery isn't necessarily well charged - it could have been sat a long time. Quote Link to comment Share on other sites More sharing options...

Had real trouble with a Series 1 many years ago and that was it. Quote Link to comment Share on other sites More sharing options...
