Changed Voltage Regulator but still low voltage?? 15 volt regulator

[Jamo]

Well the main reason is the afterrun fan kicks in after any journey where the coolant gets to 90c temp which is near any journey now as the aux rad has been removed

[Jamo]

The race is on , i'm looking to have my alternator rewired to 200amps as well at some point

Mine arrived this morning, superb service must say

[S2central.net]

Who did that work for you Jamo out of interest and was it tons of cash ?

[Jamo]

I haven't had it done yet, I had a quote ages ago from a Company Bibby used called CPS in Telford. It was £75 but I put it on hold as I switched cars.

I need to revisit and check they still can do it

[S2central.net]

Oh right - your previous post somewhat implied you had it done !!!

[Jamo]

Oops it does, sorry

[Jamo]

So the 15v reg will fit to all S2 alternators? and where did people buy them from as woodauto only sell to account holders?

guys the 15v regulator does not fit an ABY or RS2 120 amp Alternator

Will post pictures later and will phone woodauto monday

Damn... I wonder if it will fit my 3B.... (I won't find out for another 2 weeks...)

Let us know how you get on with them Jamo...

As bosch handily supplied an incorrect part number, (suggested 1197311548) and subsequently the part I thought i'd hunt for the right one and if possible the 15v version of the voltage regulator too. Quick search revealed the following:

http://www.woodauto.com/Component.aspx?Ref=VRG46410 15v upgrade replacement

http://www.woodauto.com/Component.aspx?Ref=VRG4641 14v straight replacement

3b with a/c

http://www.woodauto.com/Component.aspx?Ref=EXA2111271152

3b no a/c

http://www.woodauto.com/Component.aspx?Ref=EXA211127902

ABY

http://www.woodauto.com/Component.aspx?Ref=EXA5111021102

RS2 with a/c

http://www.woodauto.com/Component.aspx?Ref=EXA2111761202

RS2 no a/c
http://www.woodauto.com/Component.aspx?Ref=EXA211163902

Right the VR for the ABY and RS2 is VRG46402 and for the 3B it's VRG4641

I need to find the corresponding 3b 15 volt VRG46410 for the RS2 / ABY

It will fit the 3B fine

[Jamo]

Here is a pic of the difference

Will a 15v regulator cause other issues, maybe like bulbs blowing, etc?

Just wondering before I fit mine.....

It certainly will. For a standard car bulb a 10% increase in voltage causes a 100% increase in light output and a 90% decrease in life expectancy! BTW for HIDs it will make no difference whatsoever.

Your low maintenance battery isn't going to be too keen on it either.

It may have been covered in other threads but I can't see any good reason for going to a 15 volt regulator other than to squeeze a little more out of the fuel pump in a highly modified car needing that extra fuel pressure. For most of us, it's just going to cause more trouble than it's worth.

I have NOT any prob with the high volt issues; like blowing bulbs.... have done the hi volt tracks for years.... are you not shure, how high you can go: measure the acidwight in the bat...( some bat have some hidden propps under some tape) USE safety goggles, and gloves....the acid weight should bee at 1,275 or 1,280= full charge of batteri if you have the 1,21-1,24 its half charget batteri

@caterpillar, I know you're keen on 15 volts but why? It's just likely to cause more problems than it's worth?

If it was worth it, all the car makers would use it.
