Subject: [Healeys] Engine dies suddenly--solved???
Rather than replacing parts on a wholesale basis without learning what was =
the cause of the car's suddenly stopping my hope/goal was to find a compone=
nt/connection in the ignition system that appeared to be defective.
This morning I started at the key switch and it tested fine. I then moved t=
o the ballast resistor whose task is to reduce voltage to the MSD Blaster 2=
coil and the Unilite ignition module. I wanted to check the ballast's valu=
e with an ohm meter and because of where it was installed--just above the s=
tarter on the inner face of the passenger toe box--I could not get the prob=
es to the contacts, so I removed it to check it on the bench. When I unscre=
wed the bolt that held it in place a piece of its innards fell onto the flo=
or of the garage!
The Mallory 700 resistor, which along with the Unilite, has been in the car=
for 10-12 trouble-free years. It is supposed to have a value of 1.5 ohms. =
On examining its remains on the bench I could see that the coiled wire appe=
ared loose at one end and when I checked its value I got readings that were=
all over the scale. Luckily I had a spare ballast on hand--this one actual=
ly made by MSD and matched to the blaster coil--so I installed it in place =
of the old unit. I'm "cautiously optimistic" that I found the issue but of =
course that will have to be borne out by experience.
My wife likes to ride in the Healey and we like Richmond VA, which is about=
125 miles from home. The route down US 301 will keep us off of interstates=
, so we're heading down there in the morning for an overnight trip. I'll be=
bringing along a multimeter along with a spare coil, rotor and Unilite ign=
ition module, wire and connectors, etc. Hopefully all will go well. Fingers=
crossed....
