martinsaunders06 Posted March 30, 2017 Share Posted March 30, 2017 The last couple of years the Alternator on the drops has been a pain , no matter how tight the v-belt was etc it intermittently put the charge light on and belt squealed . At Xmas I fitted a complete new boxed Drops army modification kit from Daf bought from withams , in the kit it says it's a replacement for the obsolete original alternators , its a lot chunkier needing new brackets and also has new waterpump and alternator pulleys which take it from single to a double drive v-belt which is much better idea , extra wiring harness etc . Everything works ok tho up until now I'd only driven it in the yard . Driving up the road the Engine Rev counter now reads really high to the actual engine speed -2000 rpm is showing like 2900rpm ?. ? Has anyone any experience of fitting this modification in service and come across this with the Rev counter , is there a solution that is extra to the modification kit like a different tacho interface relay or rev counter ? . . Any help is appreciated thanks . Martin Quote Link to comment Share on other sites More sharing options...
martinsaunders06 Posted April 1, 2017 Author Share Posted April 1, 2017 Sorted - bit of searching and there is a tiny screw under tachometer interface top cover that trims or adjusts rev counter needle . Martin Quote Link to comment Share on other sites More sharing options...
john1950 Posted April 1, 2017 Share Posted April 1, 2017 Good find, the new alternator must be higher speed than the old. Quote Link to comment Share on other sites More sharing options...
