doesnt happen regularly. once turned on key to no lights on dash or anything. my battery conditioner will not connect to the battery terminals: no charge light shows. ordinary trickle charger ok. Had same symptoms with last battery.

Hello I'd 1st check that the main battery connections are tight and in good condition also check the earth strap to the engine / gearbox. Then follow the main positive lead back to the engine and down to the starter motor, and check the connection at this end as well.and if thats OK then check the large fuses (40A+) agin for cracked fuses, corroded contacts

Not likely to be starter motor windings or solenoid Matt?
Expert:  350matt replied 1 year ago.
Hello a faulty starter / solenoid is possible but as you mentioned the clock going slow I think its best to check the battery connections 1st
