Dynamos

One possible reason for your starter motor being sluggish is incorrect battery / stater cable specification / size - i.e. your car may have been fitted with cable bought from a local motor factors / Halfords etc for modern 12v cars - this cable is unsuitable for a 6v system. Note this spec doesn't relate to armoured cable.

I’ve posted the following before on the forum regarding battery / starter cable specification and suppliers of the correct cable and terminals. As this is a copy of an old post, the prices may have increased.

Re having the correct size of battery / starter cables for 6v – the links below take you to suppliers of the correct specification battery / starter cable to buy for a 6v system.
