Title: Ignition bypass? Post by: memper on June 17, 2013, 06:24:16 AM I have a plan to make my bike keyless. I understand the safety concerns regarding this. The plan is to have a waterproof on/off toggle near the dash area with a secondary on/off toggle in a hidden location that is in line. The starter button will also be relocated and replaced and a hex bolt head put in place of the commonly seen red button. Right hand control housing will then be removed.
My question is about switch types and amperage. For the two on/off toggles, they would be SPDT switches right? 15 or 30 amp? For the momentary switch I would need at least 7.5 amps right? Title: Re: Ignition bypass? Post by: ducpainter on June 17, 2013, 11:33:31 AM I believe you want SPST switches...on or off.
I'd buy switches of the same rating of the big fuse near the battery as you'll most likely be switching that circuit too. I think it's 30 amp. You want a switch for the starter of the same rating as the circuit it's on. I think it's on the ignition circuit on your bike. A monster uses 7.5 for that circuit. Title: Re: Ignition bypass?

Older ones drive the starter contactor directly with the start button, which draws about 8A. Newer ones just use the starter button as an input to the ECU, so naff-all current. Ignition switch powers a few amps. All the big loads (fuel pump, headlight) are via relays. Title: Re: Ignition bypass? Post by: ducpainter on June 17, 2013, 03:06:48 PM Which monster?

Typical auto shop units are a bit dodgy even when warm and dry inside a car. Title: Re: Ignition bypass? Post by: memper on June 17, 2013, 03:33:16 PM I'd recommend going the extra $ for sealed (MILspec) switches. Oh, no doubt. I have lots of experience with the crap switches from chain auto stores. Typical auto shop units are a bit dodgy even when warm and dry inside a car. I found some stainless steel, waterproof buttons at Plasmaglow. 10 amps and they come as momentary or as push on/push off (is that still considered spst but "locking"?) I just won't connect the LED which will give away my secret plan. Anyone know of something similar but without the LED? http://www.carid.com/universal-led-lights/plasmaglow-led-lighting-860342.html (http://www.carid.com/universal-led-lights/plasmaglow-led-lighting-860342.html) Title: Re: Ignition bypass? Post by: suzyj on June 17, 2013, 06:04:22 PM His is a dinosaur... ;) How is the charging circuit switched? It isn't. It's always connected directly to the battery, via the 30A fuse. Title: Re: Ignition bypass? Post by: ducpainter on June 18, 2013, 01:46:10 AM It isn't. It's always connected directly to the battery, via the 30A fuse. In that case the 15 amp switches would be adequate.Title: Re: Ignition bypass? Post by: memper on June 18, 2013, 02:55:17 AM Thanks guys/gal. So I will do two 15 amp switches for the run/kills and a 10 amp for the starter.
