Great Video…….I have a very similar problem on our spare 1993 Toyota
Corona Exsior BUT the Tacho needle was far more erratic than the one shown
in your video. It’s really ding my friggin head in.
Sometimes the Tacho would work then stop registering and rest at 0 rpm then
suddenly work again……. Its now dead, doesn’t work period!! Your video
may be of some help to me solving my problem. Its funny though as maybe 2
yrs ago a complete new distributor was installed, I am unsure if a new ICM
or coil came with the new distributor though.
How come a partially failed ICM doesn’t affect the running of the car, what
your video suggests is that IF we have a bouncing erratic Tacho needle then
the problem is down to a failing ICM that controls ONLY the signal to the
Tacho needle and yet the unit controls more than the RPM counter in the car
right?
its called thermal paste.
totally agree.
Lesson here is “Original Honda” OEM are superior and should always be
replaced with Original Honda only parts. Many buy aftermarket that looks
cleaners, shinier etc but nothing is the same as Honda Honda engineering is
so perfect many many experienced people know replacing with Original Honda
may be expensive but that part will go for another 15 to 20 yrs!! You get
your moneys worth, with peace of mind, reliability and no repeat repair
hassles with Honda OEM.
…or thermal gel, thermal compound, heat paste, heat sink paste or heat
sink compound.
Good Video on ICM Replacement.
Mine would run for 3-4 min & just shut off. I replaced entire distributor &
I was good to go.
