Ally: When it snowed the other day, I went out and tried to start my van but it just kept turning over and nearly going. It got slower and slower untill the batterry died. I took the battery out and recharged it, it's a new and powerful battery. Now it just clicks when I try to start it and doesn't turn over at all.
Is my starter motor dead? There was a burning smell after I tried to start it the first time.
HarryMann: If it didn't spin it very fast, that is what you are saying, then:
1) the battery isn't being charged up enough (generator, leaving too long between runs, short runs, poor charging connections etc.);
2) the starter motor field windings are breaking down, new starter;
3) the starter motor bushing is worn badly, creating misalignment high friction;
4) the engine or gearbox earth straps/braids & connections need checking for high resistance, breakages (can double up gearbox straps);
5) the main starter motor lead /connections needs checking for high resistance, breakages;
6) you bought a cheap or too small battery or it never really got fully charged up.
NB. Locate the source of the burning smell ASAP. Could be the starter motor armature winding insulation getting hot, or more seriously a bad earth or damaged cable. This is probably No. 1 on your list, look for smoke and check the battery connections are good (clean and use Nocrode or vaseline on terminals - and be careful with shorts/sparks when a battery has been rapidly discharged, fumes, explosion).
