just purchased a 1995 newmar kountry star. onan 6.5kw emerald plus generator cranks with the remote switch but dies when you leave go of the switch. with the rig connected to shore power, unit started and ran for about 20 seconds then switched from shore to generator and ran for about five minutes longer. unit has 212 hours on the meter. in short of taking the unit back to onan and spending a small fortune, any one have an idea where to start looking. unit has sat since 98 with limited or no usage.
