Dom Mason Posted May 20, 2015 Report Share Posted May 20, 2015 My MKI Vitesse alternator is putting out 17volts. Is there anything I can do to reduce this or should I just replace it? Can anyone recommend a good reliable replacement as the one I have hasn't got many miles on it! Link to comment Share on other sites More sharing options...
Darren Groves Posted May 20, 2015 Report Share Posted May 20, 2015 Sounds a bit high....It'll be the voltage regulator most likely, they are available, lots on eBay (assuming you have a Lucas ACR type). Never replaced one myself, so not sure how easy it is. There are uprated ACR's available on eBay and from most of the usual traders, just make sure you the cable back to the battery is rated correctly if you're going above standard. Single cable on an existing loom (if the same as Herald) is 25amp, so utilise the second large terminal on the back of the unit to share the load.

dougbgt6 Posted May 20, 2015 Report Share Posted May 20, 2015 Voltage regulator under £10 on Ebay screw fit, dead easy. Diode pack the same but needs soldering. Link to comment Share on other sites More sharing options...
