912 oil pressure sender problem

[dan3111]

I was flying last weekend the vdo oil pressure gauge went to max over worse country as normal it would have to , at this stage looks to be the sender which it 100 hours 18 months old . After talking around seems to be a common thing ,I,m had bass ring fitted and proper was balanced when sender was fitted so Didn,t save it . I'm going to remote mount it this time and try that . Sorry for the miss wording above stupid iPad two locks up and will not let me correct tithings . Mrs. Apple are doing there best to get older pads to stop working with there up dates so you by new ones they learnt of Microsoft that trick .

 

Cheers Daniel

Usualy, wen a vdo goes off the dial, the sender wire has parted company sumwhere.

 

( and no, i cant blame me ipad, i just cant spell propper. ;) )

The VDO's seem to last ok remotely mounted and isolated from vibration.

 

My direct mounted Honeywell is starting to act up at 300 hrs.

 

I would hate to think of the "Rotax" price of the latest Keller sender.

 

I'm debating whether to go the keller or remote vdo.

 

I think signal wise, they are the same?

Max reading Dan I would be looking to the wiring for and open cct first.

 

If it is the sender I am not sure but may have one. I will be up the hangar tomorrow and will have a look for you.
