Hi, thanks

I assume the battery is OK, it was fine last time it was started and turned the engine over no probs until it fired. As mentioned I don't start that often as I am in the middle of finishing it off but like to start it once in a while and get it up to temp just to make sure everything stays free.
When not running the battery is on a maintenance charger to keep it topped up and stop the alarm draining the battery.
When I turn the key to start it clicks like the solenoid has popped, the when I release the key it clicks back. It does sound like a flat battery but even if the battery wasn't at its best, I'd still expect it to turn the engine, even slowly??
I'll check all connections but from a quick check early all look good. I'll take them apart and spray on some WD40 or something to make sure all contacts are good.
Thanks again
