Re: [Amel Yacht Owners] Bowthruster Problem
Hi, You can measure the current with a clamp DC multimeter for
example DCM268 (up to 1000A in AC and DC)from Velleman Components
(www.velleman.be). Relax price is only a fraction of what You

Dear IanWith the Volt-meter and the Amperemeter clamp. Such an instrument
cost you about more the 1000$ and please calibrate it. Maybe you have
a great deal with General Electric or ABB.
If you have the 10 HP motor, it will draw around 160 amps, andwith no
forced cooling in a confined space, it will get very hot after afew minutes
operation. It is not designed for other than short bursts ofoperation.
It may be OK after a cool down period, but it's now possiblethat the
insulation will break down sometime sooner, rather than later.From what you
say, smoke comes from the motor as soon as you use it now, evenwhen cold?
Is this correct? If so, you may need to get the motor rewound bya motor
repair company. I would check the current on the Link 10 when thebow
thruster is operated. If it's much more than 160 amps, youprobably have
damaged the windings on the motor.the bow
thruster tube down a few inches and check to see if the shaftturns freely.
It may just be that you have a mechanical problem which isloading the motor
more than normal. Whilst you are doing this, check for weararound the 4
bolt holes and make sure that the countersunk screw that holdsthe brass
ring inside the tube is secure. What is the hull number of yourboat? The
design has changed recently.but I
maybe wrong. If you say that you had to over use the thruster tosave the
boat, they may be sympathetic! Good luck.----------
