Oh, right. So try a new battery first then?
I would. It's much easier that a new starter.
Hi mate, tried that with no joy, I'll try one more time tonight, if no joy then starter motor it is.
Must just need a new battery.
My Zed has fired into life 4 times since the issue post the battery being on charge and not condition mode. Took it for a quick 25m spin last night, no issues, can only have been the battery.
Or the charger?
Could be
We had one in the REME workshop. It's a seriously scary thing to use
, and not much use without the charts to compare different CCAs.
I'm sure I've seen signs outside motor factors, workshops etc advertising free battery checks. Don't halfords do it? Obviously hoping to sell you a battery.We had one in the REME workshop. It's a seriously scary thing to use
To be honest, it won't tell you anything that a battery in the car can't tell you, unless you can get one that tells you the CCA, and I've never seen one that does. They are really to test batteries that are too much hassle to fit to cars.
The CCA is estimated from the resistance of the meter and the voltage drop across the resistance.
You can get most of that info by measuring the voltage drop when you crank the engine.
The higher the CCA marked on the battery, the less the voltage drop should be when the engine is cranked.
You would think that 11.4v would be enough to start a car, but the actual voltage is not the measure. It is the voltage drop. In other words, a jump start with 14.4v that drops to 11.4v is the same as a 12.3v that drops to 9.3v. Hence why jump starting a car that has a knackered battery doesn't always work.
Look at the screen of this tool. It gives a good idea of what to look for.
A fully charged 12v 600CCA battery on this tool shouldn't drop below 10.6v.
If you want the tool, it's only £20 from Amazon...
Only really applies when the starter is working, and the original post was a non-starter. And in the right hands a tester isn't that scary, just got to know what you're doing.
I have got one of those and it has come in usefull several times on my cars and others.We had one in the REME workshop. It's a seriously scary thing to use
