General Discussion / Chinese generator wiring
July 02, 2018, 06:01:56 AM
Hi Fellas. I recently bought a 6500 watt electric-start petrol generator at a clearance sale - sight only, not able to be tested. Funnily enough everything worked fine - no issues but a bit rough 1st glance. Pumped up the tires, bashed out the dents and tidied up the wiring and paint and welded on a few lifting eyes as it's a heavy sucker. I decided to fit a 16 amp outlet on the main panel to allow hooking up to my caravans main cord. Upon tilting forward the front panel I was confused with the wiring colour/plug orientation so hooked out my Fluke and with the generator running checked it out. WTF! All three single phase outlets had phase and neutral transposed. This generator had been sat on an engineers truck, out in the elements for a few years running his Caddy's and other power tools no issues. God help someone had hooked up to a switchboard with MENS wiring. (or an old caravan). How many thousand of these are floating around out there with "To whom it may concern" hovering around them? ::)

Hi Fellas. I finally took the time to learn how to deal with photos/movies in forum sites. Here is my 1st effort. https://youtu.be/5I5RUfIjIc4  .  This is my 1972 Lister SR2 6kw self/start standby genset.  It is ex - NZ railways signals standby and was permanently wired into both national grid and signals single phase supply. As is to be expected upon power failure of grid this unit would disconnect from grid and simultaniously run up to full speed and restore 230v supply to signals. Reverse would happen upon supply being restored along with a time/down. It has automatic decompression/valve unloading both ways. Batteries are 2 x 12v deep-cycle in series for startup and excitation and it has its own self-charger. I fabbed the trolley, high-level fuel tank and the exhaust system for ease of shifting around the garage (excuse the mag-wheels as all I had in stock). As with any Lister, this starts 1st time every time with hand-cranking. Very noisy as typical of air-cooled diesels so am selling/swapping to get a Lister 5/1 or larger for home project generator using a Fisher and Paykel washing-machine motor converted to generator. I hope you enjoy the video. Cheers.

Hi Fellas. What is the proceedure for fitting an oil pressure guage to a Lister SR2 (tapping in point etc) ? Can you remove the pulsing generated by the plunger type oil pump ? What is considered good pressure? Cheers.

Hi Fellas. Just aquired a Lister SR2 # 5471 (256 hrs) attached to a Brush generator (6kw) # 2/57635. This was a standby generator for New Zealand Railway signals. I would like to correspond with a forum member with a similar set up. The engine would have to be between 1967 and 1976 I would guess but I havent the resources to track engine no. to a year of manufacture. The set-up came straight out of service last week and came complete with all switchgear/batteries/control board etc. I proposed to fit it up to its own trailer as a mobile unit for ease of moving around my garage but another member of the forum suggests the only way to mount these is to a block of concrete to prevent winding degradation. Any help much appreciated. Cheers, Derb.
