Re: (ET) Trace Inverter mounting on ET

["Monty McGraw" <mmcgraw74 hotmail com>]

Dave,

I have a Trace 1524 - same size as 3624 that I've used quite successfully
with my I-5.

I put it in a Sears garden tractor tool-bin, that I've attached to the back
of the ET.  I put in a cutoff switch inside the tool bin - for a safety
disconnect, and wired the inverter to the four rear batteries.

In use, with the tractor parked, I prop open the lid of the tool-bin so the
inverter gets some air circulation, push the inverter power button, plug
into a receptacle box I wired to the inverter output, and chainsaw away.

My I-5 actually has a small Anderson connector bolted to the rear of the
right fender - but it is currently wired for full 36V.  If I rewire that
connector, I'll be able to make the inverter a pluggable option for my ET.

No problem running my Husquvarna Electric Chainsaw :)
