In my BMW i use one Bosch relay to turn on a multy componnent system so i wanna know if the relay can handle one more item,like an Cyberdyne digital voltmeter gauge.I have 4 amps,one eq,one active crossover,cap charge indicator,capacitor voltmeter (in trunk).The new gauge will go in my glove box so i will know how much juice i have in my Optima RedTop.So that's 8 pieces of equipement,will it be OK,i used my HU remote wire not the power antenna so i'm hopping ...my relay it's also fused.

Thank you Relay ,unsure ... - Last Post -- posted image.

As long as your components don't draw more than 20 amps, test with meter, than you should be fine.

if you use a 40 amp relay which most bosch are and use a 30 amp fuse than your fine even 30-40 amps is a lot for turn ons that need like two.

Hi,the relay i used it's one of those SPDT (single pole double throw...i think they call it) made by Bosch.I don't know how much all components draw amp wise,but prong # 30 on the relay it's fused with a 5 Amp fuse,should i increase the fuse rating ?,it's never blown yet.

Then that means that you’re not currently pulling more than 5 amps from your relay. So you will not have a problem adding a few more devices. My advice to you would be to leave the 5 amp fuse and if it blows when you add the voltage meter than increase the size of the fuse.
