OK brains trust
History - had the van unstarted for about 2 months, started fine off the key [ the battery is quite new ] drove for about 1 hr left standing for about 15 min and it sounded slow off the key but started ok, drove for about 30 min stopped for 3-4 hrs and slow off the key again but started, left standing for about 10 min and then all l got was very slow motor turning off the key and it was roll start time !! and now that is all l get. Charging is ok and bat v is good. all connections are tight.
my question is could the problem be the contacts inside the solenoid?
should my next move be to bypass the solenoid and put 12v direct to the starter and if successful will this confirm my suspicions
cheers
