View Full Version : starter boost relay kits--what are they?
Lately I've run across what are termed "starter booster relay kits", or words to that effect. These seem to be a relay, inserted in series with the starter solenoid.
Are they to boost a weak solenoid? Don't see how they could boost a dragging starter. If they are to boost a weak solenoid, how does this happen?

The only thing a starter relay does, is to use a low current coil to close electrical contacts in the high current/power circuit that your starter demands.
I axed a search engine(dogpile) about the starter booster and this is all I found:
WOW! that's kind'a long ain't it!?

I previewed the above reply before posting it and the URL was like 3 full lines long, so if the link does not work let me know.
hello , starter relay is usally installed to supply full batt voltage to solenoid windings.The reason for doing so is, original wiring is suffering from voltage drop therefore not suppling full voltage to solenoid windings and effecting pull in operation of solenoid plunger.The relay is wired "pwr side" fused supply from batt ,output to original solenoid spade."siginal-coil side"input wire,from original loom ,output wire to earth.Ther are exeptions to this rule , check with auto elec . tomo
