Default Neat old 2-71 GM Diesel

May well be 1200 rpm. Saw this ad and figured folks would enjoy looking at it. Ad is written like an ebay ad lol. Sure wish we could see that nameplate in the bottom corner of the third photo...

prolly rated 12.5 KW, might be able to make 15 or 20 KW if it's a particularly frisky set. 100 RV's and the park too? nah....lol

The railroad ones were 12 kW, but this one looks different than those. Usually 20 kW if 1200 rpm, 30 kW if 1800 rpm. The 100 RVs must be only when their A/Cs aren't on.

Tag says 32v dc. Also note the four 8 volt batteries and you sure don't need that much power just to crank a 2-53. I'll bet it was backup or charging for a telcom system.

Telcom is 45 volt, not 32, tho I have seen a telco set use 32 volt cranking for no apparent reason.

I was guessing marine use maybe. RR use doesn't seem to fit, but who knows.

I -THINK- it's just 32 volt cranking, but not sure on that.

Actually, most Telcom Battery Systems are 48Vdc... with Regulated AC Charging Systems run from Grid Power and Genset Backups....
