Trim Tabs - Tony Saitta - 09-25-2018
Trim tabs on Tiara 3800 Open do not open. Bennett Pump oil is full.
Is there a relay switch associated with the switches on the dash? If yes then where is it located?

could be fuse on dash......(where are the other fuse resets are) or relay mounted down near pump.

Last Bennett system I worked on had no relays. 12V ran direct from switch panel to reversing motor and valves in the pump. Regardless first check for fuse/breaker per previous post, then check for 12V at pump.

[attachment=466][attachment=467][attachment=468][attachment=466][attachment=466]Bennett Trim Tabs on Tiara 3800 open would not open. We finally found that the problem was the faulty Charles Industries 12/24 V EMI Suppressor. I cannot find a replacement part as Charles Industries no longer make them. We found that the trim tabs opened when we bypassed the suppressor. A couple of questions:
1) Are there any negatives if we bypass the suppressor and
2) Does anyone know if there is a similar replacement for the Charles Industries part?
3) Is there somewhere to find a second hand one.

Where is the Charles EMI Isolator located?????? Don't remember seeing IT on on my 2003 38 OPEN
RE: Trim Tabs - Tony Saitta - 10-05-2018
The EMI Suppressor is located next to the trim tabs pump, aft where all the auto pilot steering gear is located

I have the same issue, to bypass it did you just connect the "Ins" to the "Outs" ????
Thanks.

Did you by chance find a replacement? My 2001 3800 Open tabs won’t go down either. I can hear it buzzing but the tabs aren’t moving.
