Discussion:
no 3rd speed

I have an older series M walkie lift. The 3rd gear isn't working. In the past it was usually just a switch or wiring problem in the handle. This time the connector switch B doesn't seem to activate, it just seems to rattle back and forth and doesn't make contact. Any help appreciated.

Showing items 1 - 3 of 3 results.
you can also check for debree in the contactor as the terminals on the contactor for the coil frequently drop out. I have even had occasion when a piece of plastic has logged between the tips. Third speed switch above the 3rd speed contactor also suffers from dry or broken solder on occasion. Rabbit switchs are also notorious for internal corrosion or failing contact.
But i think Tony may be right, low voltage is the most common cause.

If the batts are o.k., check harness that runs under/by the drive tire. I have seen alot of them chaffed. 3rd speed, meaning no contactor movement? (high speed contactor-the one with the switch mounted to it?) check negative voltage.

Sounds like the batteries need a charge or there is one or more bad batteries. I would check them with a volt meter while operating the lift to put them under a load.

Fact of the week
The dot-com bubble, a period of large and rapid investments in internet-based companies, peaked in 2000 and saw the Nasdaq Composite index rise by 579%. Then the bubble imploded. As the value of tech stocks plummeted, cash-strapped internet start-ups became worthless and collapsed.
