Several months ago, after a discussion
with Tracy, I ran
grounding straps from each battery to the PSRU plate on both sides of the
starter mount. I had previously had the grounding strap running between
the center iron and the “forest of tabs” grounding block on the firewall.
Tracy suggested
I move it so the starter amps would not get into the grounding block.
Now I have the igniters grounded on the
center iron and I am considering running a ground strap from the center iron to
the batteries or trying to tie each section of the engine “sandwich”
together by running a wire between them. This would to be certain that
the ground is good on the igniters.
Any opinions on this??

As Mark says + make sure you have a ground cable/strap connected battery direct
to your starter. Do not expect starter to ground through your engine without
problems.
I remember Tracy
posting on this issue years ago just a bit hard to find in the archives now.

Bill,
You may want to check your engine ground. Starter current may be
causing this.

I am working on cleaning up my ground system and I noticed that I have
several, 3 or 4, places on my SS braided fuel hose that appears to be burnt
like it had an electrical spark exit from it. I have not found anything
in
the vicinity of these places that look like where the spark? would have
jumped??
Has anyone seen something like this and what should I do about it? Do I
have a ground problem in the engine compartment or is this maybe static?
The hoses are covered by SS and are connected on one end to a filter that
has a ground strap on it and on the other end to the fuel rail which is
grounded to the engine.
