harrison l5 start gear

Hi all I got a fairly run down l5 that I have been doing up. It seams the contact points coil jumps back up after pressing start, the contact points are also arcing. I'm running a 220v single to 3 phase inverter from ebay. It work if I hold down the contact points plate. Any ideas? I may just clamp the top plate down and just run it from the switch. my inverter says 220v 3ph but I guess that's just per phase voltage?

the inverter is

You really need to wire the inverter direct to the motor and not through any of the lathe switchgear.

ive converted a couple of L5’s to run from inverters, and in each case had to dig the star point out of the motor.

so unless yours has had the motor swapped at some time to a star/delta motor, you will need to do the same.

hi alan

ok i get that. if its not wired in delta would it still run ? as mine runs fine with holding down the contact points plate its a 1958 l5 with the stock motor. its just the contact points plate wont stay down after pressing start

I Think it will run, but not properly, probably find it will stall under load, never tried it to be fair.

whip the motor cover off and see how many wires are coming out of the motor, you need six.

Have a read of this Thomas **LINK**

only 3 wires come out to the junction box, so i assume its in star and i need to find the joins and reconfigure the windings to delta ? yea didnt seam very strong to be fair

no, thanks very much !

Yeah, they are dead easy to do, strip the motor and star point is fairly easy to find....... Well it was on the ones I did anyhow.
