Sterling Regulator

[Askival]

I have purchased the Sterling pro digital regulator and remote control, I have soldered two wires to the alternator as stated in the installation guide, (this is to identify the field wire) one wire reads 14 volts the other wire reads 0 volts. I took the alternator to an auto spark and the alternator is working OK, he also stated that the voltage readings where what they should be 14 & 0. I cannot get reading 2-10 volts from either of the wires as per the Sterling installation guide. The only terminal on the alternator that gives a voltage of 7 volts is a spade terminal with a purple lead apparently for a tachometer, has anyone installed this regulator and had the same problems?. The alternator is a Valeo 35 amp and is new.

I have fitted a couple of Sterling regulators without any problem, I suggest you contact sterling direct. They have a very good help line.

I installed a Sterling with exactly the same alternator as you, and I seem to remember the voltages were 14 and 0 as you found. Worked fine, no problem.

Thanks for the reply, what wire did you connect to the sterling white wire the 14 volt or 0 volt? according to sterling you only keep one of the wires that you solder to the brushes and this is the one you connect to the sterling white.

Aaaargh you've got me there. I fitted this a year ago to a boat I sold a month ago. All the paperwork including the fitting instructions for the Sterling went with the boat. Didn't you have to connect the white to the wire showing 10-12v, the other wire being much lower or even zero? I do strongly support the other response you got, that if you're in doubt, give Sterling a call. Despite what some other people have said in the past, I've found them helpful. Sorry I can't give a definitive answer.

What type of.....

meter are you using. Digital or an analogue with a needle?

It needle type it could be that you aren't able to determine the fluctuating voltage clearly enough or your battery might be so flat that a full 14v is going into the field to charge it so a voltage of around 6 to 13 isn't being revealed on the appropriate wire as described. Also, although the instructions talk about a "high Idle" (or somesuch) IME normal tickover gives the best results.

If in doubt, give Sterling a ring. I have always found them helpful
