[Vwdiesel] Wiring a VW alt in tandem with another

[lbaird119 at aol.com]

For years they used a light bulb (idiot light).  Then we started using LED's and to make it excite a at a little lower rpm you can tap in another diode in parallel.  Gotta wire it the right direction so I'd probably use an idiot light.  Properly observed, they're a pretty good diagnostic tool for alts.  :-)

 almost have my JD L&G tractor wired up to run my VW alternator off the rear 
TO (front PTO drives the snow blower). My question is on the exciter wire-does 
t need to have a diode on it or can it just be a switched power source that can 
e turned on and left on while running, or should it be a momentary switch to 
xcite it and then turn off? I am pretty sure the rest should be easy just 
aving the two alternators and batteries in parallel. The tractor alt has just 
nough power to run the PTO's and other functions to keep the tractor running so 
he VW alt is for the addition of the cab and its functions (wiper, heater, fan, 
ights, etc). I will have another battery in a ballast box behind the tractor 
go figure-a vw rabbit battery). 
So-diode, momentary switch or just on/off switch for the the exciter wire.
