12.5 Kohler Gen set Instruments

[GARY MINKER]

some of the meters have 12 volts feeding the meter and some have a ground connection. they are not all fed the same way. this is pretty silly but it is the way they did it. all meter function is triggered by the control box. if the generator is not running or trying to run, troubleshooting the metering is tricky. if the metering is not running, it may also shut down the engine. it is a real catch 22 trick --- On Tue, 2/3/09, Chuck Wheeler wrote: From: Chuck Wheeler Subject: RE: [WanderlodgeForum] 12.5 Kohler Gen set Instruments To: WanderlodgeForum@yahoogroups.com Date: Tuesday, February 3, 2009, 11:45 PM The Oil pressure sending unit is on the right side of the engine low down about 2/3 back from the front. The temperature sending unit is on the top front near the upper radiator hose. I have the resistance of the units at home but we are on the road right now. I would expect a wiring problem since they both are not working. It is easy to pull the leads off them when work is being performed on the genset. - Chuck Wheeler- 1982 FC 31SB Fort Worth TX From: WanderlodgeForum@ yahoogroups. com [mailto:Wanderlodge Forum@yahoogroup s.com] On Behalf Of akav8r Sent: Tuesday, February 03, 2009 9:16 PM To: WanderlodgeForum@ yahoogroups. com Subject: [WanderlodgeForum] 12.5 Kohler Gen set Instruments I have the 12.5 Perkins/Kohler Gen set. The only "engine" instrument that works is the Volt meter. Can anyone help with the location of the sending units on the engine for Water temp and oil pressure. I have checked the gnd at the instrument panel and got no results, this could still be the problem. I see several sending units on the engine but am unsure which ones are tied into the auto shut down and which go to the instruments. Also if anyone can help with a procedure for testing either the instruments or the sending units. Any help is greatly appreciated. THANKS Wendel 82 FCSB 35 "Change of Venue"
