[urq] Intermittent no start, now a weird intermittent start.

[Wylie Bean]

If it's been sitting and not at a relatively full charge you could have killed a cell or have plates corroded together inside,  esprcially if it's gotten low on electrolyte. Had it happen on stored motorcycle's battery.

I've now re-checked the connections at the battery and the solenoid and I 
have removed and cleaned up the connections at the alternator but to be 
honest they were shiny clean anyway. Put it back together and tried again. 
Started first time. But struggled a second time. Third time wouldn't start. 
Just turned over in a very laboured way. It doesn't spin-up like I think it 
should even when it starts.
The battery is not very old at all. Perhaps 18 months, but the car has been 
inactive for a good part of that (off road due to head gasket blown and lazy 
owner). Could it be that although it shows a respectable voltage, the 
battery just can't put out the power because of something caused by it not 
having been used for a long time and perhaps the lack of oomph was a 
contributary cause to my original intermittent non-start?
I'm at a loss really. I guess I need to either buy a new battery or at least 
get this one tested for power output to rule that theory out.

Latest update - before I start removing wires and cleaning up
terminals/connectors.
The connections to the battery are good, clean and secure.
The connections to the alternator and starter are good and secure but yet to
be determined if they are clean.
The solenoid has a heat wrap on it (from my old starter) and my exhaust is
wrapped in heat proof bandage and I haven't been on long trips so I don't
think heat soak is an issue.
I put the meter on the battery - 12.33v With the ignition on, this drops to
around 12v. When I start the car (it started first time!) the voltage
momentarily dropped but once running and stable the meter showed steady
12.6v.
Going to have a look at the alternator end of the leads and see if these
need cleaning up. In doing the head gasket job the only wiring I have
disturbed (to do with starting) are the earth wires to the cam cover, the
starter wires, the battery terminal connections and that's it. Are there any
other main earth leads from the block? Those two wires to the cam cover
don't seem enough.
Will update when I know more but any further suggestions welcomed in the
meantime.
Cheers

Sometime ago I put up a series of posts about an intermittent no start where
it sometimes would start fine and sometimes I’d turn the key and nothing
would happen, not even a click. However if I rocked the car a bit whilst in
gear, it would start. Not only was this a pain when it happened it was a bit
embarrassing too. I put up with it for far too long.....because it was
intermittent.
Anyway after getting it all back together and up and running following the
head gasket job I resolved to purchase and fit a new starter motor which I
did today. (had a day off work quattro day in the sunshine!).
Now the new starter turns every time and whirrs nicely like a starter on a
modern new car but..........after initially starting reasonably well the
next time it turns slowly like the battery is run down and doesn’t fire. So
I charge the battery up which surprisingly didn’t take long so it couldn’t
have been too low. This time it fired up. I went for a short drive, came
back, switched off. 5 Minutes later tried to start it and it turns over
slowly like low battery but won’t start. Battery showing 12.33v and when I
put it on the charger it shows fully charged. I am not great at diagnosing
electrical faults. Fine at repairing them but not good at identifying them.

Anyone have any ideas what’s going on. Sorry to be monopolising the list at
the moment but having a beautiful car and wonderful weather.....yes that’s
right wonderful weather in England...I’m really disappointed not to be able
to be out enjoying it on the open road. So if you have any ideas, as usual,
I will be most grateful. Many thanks.

All the best
