So I've just tried to start my newly built 2276… 10.2:1 CR and it doesn't crank very well at all.
So slow that the ECU doesn't even see it's cranking. With no rockers or spark plugs it'll turn over at 200rpm, which is enough for the ECU to fire the plugs.
Remade the connections on the starter, fully charged 063 battery, 44 Ah, 330CCA
The starter bush is only 3000 miles old too.
I have a stock (old) starter, so guess it's met its match but before shelling out I would like some input please guys!
Less than £50 will get me a new, bigger battery with 550CCA and 60Ah from Halfords but not entirely convinved that'll fix the issue.
I've remade the connection from the battery to the solenoid with 25mm2 cable, also replaced the spade terminal on the other connection. I have't touched the link between the starter and the solenoid. I will do that.
The starter spigot that mates with the gearbox is clean and free of paint/crud.
The earth strap from the battery to the body is brand new 25mm2 cable, as is the earth strap from the gearbox to the frame horn.
Auto starters, who's running one and where from?
They're only 0.8hp though compared to stock 0.7hp. Is that a worthy upgrade?
Alternatively, there's the Wosp high torque from just over £200 that produce 1.3hp...
Sorry that's a lot to hit you guys with... Any input would be hugely appreciated though
