I was wondering if anyone has come across a cheaper 40amp alternator for the X595 (Yanmar) diesel engine. The JD upgrade for $400 is too much.
A cheaper 40 amp Alternator for my X595?

I thought I would update this thread on my findings.
I need more power based on a sprayer I would like to use.
An unfortunative cost of the upgrade is a simple adapter cable to the dashboard. Unless you can live without the alternator warning light, this adapter cable will "rewire" the dash to allow a self-regulated alternator to be installed.
The current JD design has the alternator warning light grounded internally to the dash. When problems are sensed during charging the external regulator sends 12vDC to the dash to energize the light.
The adapter cable rewires the warning light by swapping the ground with 12vDC. This is because the new internally regulated alternator will ground this circuit if problems are sensed. It is completely the opposite from the original design.
If you can live without the warning light you can upgrade with charging system as cheap as $140 US. If the warning light is important to you, you have no choice but to buy the adapter cable ($80US) to complete the job. So $225 is still better than $380 from JD. And you would be using the same installation harnesses etc. found in the kit.
(Obviously one can cut into the factory harnesses to perfrom the mod. I am not a fan of permanently modifying anything on the tractor to support this upgrade. You can perform the upgrade without permanent modifications to your tractor.)
I have found a source in Tenn. that offers new Denso 45amp alternators for $125 shipped.
I can can provide more details if other TBNrs are interested.
Thanks to JoeDeere for his help on this upgrade.

I cut the wires to the light and put a weather pack connector in line that I can re-pin if I want to go back to the original alternator. All other wires were connected at the plug for the existing voltage regulator under the dash without having to cut into the tractor harness.

yup, That is one way of solving that wiring problem. With my tractor still under warranty I did not feel comfortable making a modification like that. But out of warranty I would seriously consider your mod.
Yes, using jumpers at the regulator plug is the other half of rewiring the alternator.

Good point. I waited until the warranty was up before I installed the alternator.
