TR2/3/3A How many ground straps on a TR3A?

[Bremer]

Hi folks, just wondering what is actually grounded with a ground strap.
I know about the chassis to engine strap by the LH motor mount that connects to the front engine plate. But how does the chassis get ground? Is there a body to chassis ground strap? If not, would it be a good idea to add one?
What else needs to be grounded separately? I remember a post about the steering column having a strap (but that might have been for a TR4, pardon my ignorance).
Thanks!

I don't know a thing about TRs but I would say

OK I had to say it. It goes with my, When in doubt throw it out mentallity, when it comes to my wifes stuff.

There is no separate strap between body & frame AFAIK; only the several bolts that hold the body to the frame. But they seem to be adequate; I didn't notice any change in cranking speed even when I ran a battery cable directly to the engine block.

No strap needed for the steering column on a TR2-3B. However, there should be a ground harness to the speedo and tach head (for the lights); and I advocate adding grounds for the fuel gauge, fuel tank sender, and all of the lamps in the rear.
Oh yeah, there should also be a ground wire for the wiper motor. It's used only by the park switch, but it's still a good thing to have.

There's also a small grounded wire on the firewall between the battery and the voltage regulator

Thanks everyone, this confirms that my LBC is not missing any straps. Depending on how it behaves during start-up I might add more grounding cables.
