Search was inconclusive. Car's an 83 300D, 190K.
My glow plug indicator is starting to flicker once in a while, most noticible in the morning. Car starts fine. Can't tell if the flicker is from wiggling the key or not. Does the glow plug lamp indicate any type of GP health in this car? Would a getting ready to fail relay do this? Car started this morn at 14F without block heater so I am thinking the GPs are pretty much OK.
Thanks for any and all advise.
