re capacity of lofrans tigress
i have one of those windlasses i assume 37 yrs old on a
jeanneau with 55lb spade/12mm chain , at and 100 ft of
depth will easily
lift it all off the bottom.
with the high amperage you mention i would inspect
1-if its a newer unit that you have a 24volt motor running on 12v system
2-if it is an older unit i would inspect for a
wiring issue high resistance low voltage etc starting at the motor measuring amperage and voltage under load
3-and then possibly the motor itself
brushes winding fault etc
4 i have also seen the main shaft on those windlasses get twisted if severely loaded if that causes binding it will also increase the amperage reduce the
power .
when my tigres slowed down got weak i started the
inspection at the
wiring. measured voltage and
current under load. with lower voltage and higher amperage than expected can't
recall the numbers sorry . found lots of wiring problems . it turned out
jeanneau had installed the 90 ft of cable to the windlass in a smaller gauge than required. much too difficult to replace so installed a
battery in the bow to boost voltage and lower draw that helped. as someone here mentioned running the
engine at high idle for a few minutes prior to and during use really helps keep the voltage up.
what ended up being the main problem was
oil that had leaked past the rear windlass seal and into the motor mixing with the graphite dust and rust to make a sludge that produced tremendous friction in the motor from armature rotating in that paste as well that paste caused the
brushes to stick. the
oil seal had been installed incorrectly allowing
oil to leak past
it is important to get all the pieces between the motor and windlass
gear in the correct order on reassembly. my windlass was not assembled in the correct order. you mention the brushes moving freely. you may want to check they are not sticking at the bottom of slide and that the connector is allowing them enough range to seat easily on commutator. that does happen as the brushes wear down . on those motors which are very reliable the most common problem is brushes hanging up. if you need brushes that aren't available locally you can grind or file down larger bushes till they fit the slide.
there are i believe three different 1500 was motors available for that windlass with two different shaft sizes to sort those variables out you need the
serial number of the windlass or date of manufacture and or the shaft size the newest motors come in two pieces not one piece as in the past now you have to
purchase the correct flange as well as the motor base
if you are on the
west coast of
canada ReKord/victory have the newer motors and flanges in stock as well as the
rebuild kit for the tigress windlass including the
seals they are not sure if they have the older motor with the different diameter shaft in stock.
i can check the voltage and amperage at my motor in loaded and unloaded state if you wish
