Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

After swapping multiple parts, the owner's rectifier looked to be fine under warm temperature but not sure when it got hot.

And even with just the appearance, already big question mark with the regulator although no 'charging' warning light.

Using my old regulator and the rectifier showed much better load test result.










Before replacing the battery, measured the dark current and didn't see any abnormal consumption.

But with the IGSW in P2 and while engine running, thought about excessive current consumption caused by failed relay, system, etc that could trigger this type of issue.

But then that doesn't explain why using my old regulator and rectifier showing different load test result.

Any way, not sure this is normal with the classic ABS but these two failsafe relays got fairly warm.

I already upgraded to the latest ABS so can't confirm it using my NSX.

The blower high speed relay will get hot because I forced the speed setting at max.

There is another relay dedicated for the non-max speed setting with the pwm control on the power Tr for fan speed control.












After testing so many combinations and scenarios, the decision was made to temporary use my old regulator as an on-loan item and
although the rectifier looked to be fine, didn't want risking when it gets hot so replaced it with the new aftermarket one.

Returned the original components to the owner.

Should survive until the next visits.
