Surf Electric Problems

[shillito]

Hi can anyone help i have a 1992 surf turbo diesel i just had a new head fitted and since i got it back i have had problems with the electrics i returned to the garage and they said the batteries were knackered so i bought two new batteries still the same problem. When i turn the ignition on my rev counter goes potty then it settles down i turn the key and she starts up i drive 2 or 3 miles turn it of and it wont start again, jump it from another Battery and it starts no problem, the alternator has been checked out ok i am at a loss obviously something has not been put back right when the head was done i need HELP. I am disabled and use a wheelchair i have contacted the garage but no response, i am stuffed without wheels any suggestions would be welcome thanks Bill. :

Something draining the batteries then. Could be that the earth strap from engine to chassis is broken or not reconnected. Check the earth terminals on the batteries are tight..
