Electrical Failure on Take Off

[kevin]

Can I get Allie Cat to fix my transmission?

Kevin:

Is that a euphemism for what I think it is? You dirty, middle-aged man! I'll see to it that she has no part of your "transmission" in the Keys, thank you very much!

I just got my 337H back from annual. The failure was the high-low
sensor that is mounted in the center console below the throttle quadrant. Thats why the DIS light would not go out. Dale Campbell

Thanks for the update Dale.

There you go Dale,
Saw this problem on a 337G a while ago and the alternators going off line was more that likely caused by FOD going thru the rear alternator, caused a short inside the alternator for a second but enough time to cause a Hi volts which took out both alternators.
The rear 35A circuit breaker had popped and the HI/LO sensor had been damaged.
The circuit breaker was restored and the alternators ran fine, but the DIS light was on all the time. The HI/LO sensor was replaced and the system check out ok.

BTW a search of the rear engine bay was done nothing found, a look at the alternator turned up the same.

Glad to hear everything ok

Can anyone please tell me where is the Hi/Low sensor located?

On a T337H they are located under the pedestal cover on the right side
