Where can I find a Westwood Lawn tractor workshop manual?

I have a westwood 1600H35 lawn tractor that has recently been serviced and will now not start having run just once for 6 hours. I have changed the battery (45 Ah) and attempting to clean all the contacts and electrical connections. I would like to obtain a workshop manual (esp electical circuit diagram) ASAP in order that I can take the thing appart and ensure it goes back together, before the meadow becomes too overgrown or I kill my lawn mower..
